- If an error response is returned by Amazon
Kinesis Streams indicating either a problem with the data in
the request, or a server side issue.void createStream(CreateStreamRequest createStreamRequest) throws AmazonClientException, AmazonServiceException
Creates a Kinesis data stream. A stream captures and transports data records that are continuously emitted from different data sources or producers. Scale-out within a stream is explicitly supported by means of shards, which are uniquely identified groups of data records in a stream.
You specify and control the number of shards that a stream is composed of. Each shard can support reads up to five transactions per second, up to a maximum data read total of 2 MB per second. Each shard can support writes up to 1,000 records per second, up to a maximum data write total of 1 MB per second. If the amount of data input increases or decreases, you can add or remove shards.
The stream name identifies the stream. The name is scoped to the AWS account used by the application. It is also scoped by AWS Region. That is, two streams in two different accounts can have the same name, and two streams in the same account, but in two different Regions, can have the same name.
CreateStream
is an asynchronous operation. Upon receiving a
CreateStream
request, Kinesis Data Streams immediately
returns and sets the stream status to CREATING
. After the
stream is created, Kinesis Data Streams sets the stream status to
ACTIVE
. You should perform read and write operations only on
an ACTIVE
stream.
You receive a LimitExceededException
when making a
CreateStream
request when you try to do one of the
following:
Have more than five streams in the CREATING
state at any
point in time.
Create more shards than are authorized for your account.
For the default shard limit for an AWS account, see Amazon Kinesis Data Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To increase this limit, contact AWS Support.
You can use DescribeStream
to check the stream status, which
is returned in StreamStatus
.
CreateStream has a limit of five transactions per second per account.

Kinesis Streams indicating either a problem with the data in
the request, or a server side issue.void deleteStream(DeleteStreamRequest deleteStreamRequest) throws AmazonClientException, AmazonServiceException
Deletes a Kinesis data stream and all its shards and data. You must shut
down any applications that are operating on the stream before you delete
the stream. If an application attempts to operate on a deleted stream, it
receives the exception ResourceNotFoundException
.
If the stream is in the ACTIVE
state, you can delete it.
After a DeleteStream
request, the specified stream is in the
DELETING
state until Kinesis Data Streams completes the
deletion.
Note: Kinesis Data Streams might continue to accept data read and
write operations, such as PutRecord, PutRecords, and
GetRecords, on a stream in the DELETING
state until
the stream deletion is complete.
When you delete a stream, any shards in that stream are also deleted, and any tags are dissociated from the stream.
You can use the DescribeStream operation to check the state of the
stream, which is returned in StreamStatus
.
DeleteStream has a limit of five transactions per second per account.

Describes the specified Kinesis data stream.
The information returned includes the stream name, Amazon Resource Name (ARN), creation time, enhanced metric configuration, and shard map. The shard map is an array of shard objects. For each shard object, there is the hash key and sequence number ranges that the shard spans, and the IDs of any earlier shards that played in a role in creating the shard. Every record ingested in the stream is identified by a sequence number, which is assigned when the record is put into the stream.
You can limit the number of shards returned by each call. For more information, see Retrieving Shards from a Stream in the Amazon Kinesis Data Streams Developer Guide.
There are no guarantees about the chronological order shards returned. To process shards in chronological order, use the ID of the parent shard to track the lineage to the oldest shard.
This operation has a limit of 10 transactions per second per account.

the request, or a server side issue.GetRecordsResult getRecords(GetRecordsRequest getRecordsRequest) throws AmazonClientException, AmazonServiceException
Gets data records from a Kinesis data stream's shard.
Specify a shard iterator using the ShardIterator
parameter.
The shard iterator specifies the position in the shard from which you
want to start reading data records sequentially. If there are no records
available in the portion of the shard that the iterator points to,
GetRecords returns an empty list. It might take multiple calls to
get to a portion of the shard that contains records.
You can scale by provisioning multiple shards per stream while
considering service limits (for more information, see Amazon Kinesis Data Streams Limits in the Amazon Kinesis Data
Streams Developer Guide). Your application should have one thread per
shard, each reading continuously from its stream. To read from a stream
continually, call GetRecords in a loop. Use
GetShardIterator to get the shard iterator to specify in the first
GetRecords call. GetRecords returns a new shard iterator in
NextShardIterator
. Specify the shard iterator returned in
NextShardIterator
in subsequent calls to GetRecords.
If the shard has been closed, the shard iterator can't return more data
and GetRecords returns null
in
NextShardIterator
. You can terminate the loop when the shard
is closed, or when the shard iterator reaches the record with the
sequence number or other attribute that marks it as the last record to
process.
Each data record can be up to 1 MB in size, and each shard can read up to
2 MB per second. You can ensure that your calls don't exceed the maximum
supported size or throughput by using the Limit
parameter to
specify the maximum number of records that GetRecords can return.
Consider your average record size when determining this limit.
The size of the data returned by GetRecords varies depending on
the utilization of the shard. The maximum size of data that
GetRecords can return is 10 MB. If a call returns this amount of
data, subsequent calls made within the next five seconds throw
ProvisionedThroughputExceededException
. If there is
insufficient provisioned throughput on the stream, subsequent calls made
within the next one second throw
ProvisionedThroughputExceededException
. GetRecords
won't return any data when it throws an exception. For this reason, we
recommend that you wait one second between calls to GetRecords;
however, it's possible that the application will get exceptions for
longer than 1 second.
To detect whether the application is falling behind in processing, you
can use the MillisBehindLatest
response attribute. You can
also monitor the stream using CloudWatch metrics and other mechanisms
(see Monitoring in the Amazon Kinesis Data Streams Developer
Guide).
Each Amazon Kinesis record includes a value,
ApproximateArrivalTimestamp
, that is set when a stream
successfully receives and stores a record. This is commonly referred to
as a server-side time stamp, whereas a client-side time stamp is set when
a data producer creates or sends the record to a stream (a data producer
is any data source putting data records into a stream, for example with
PutRecords). The time stamp has millisecond precision. There are
no guarantees about the time stamp accuracy, or that the time stamp is
always increasing. For example, records in a shard or across a stream
might have time stamps that are out of order.

- If an error response is returned by Amazon
Kinesis Streams indicating either a problem with the data in
the request, or a server side issue.GetShardIteratorResult getShardIterator(GetShardIteratorRequest getShardIteratorRequest) throws AmazonClientException, AmazonServiceException
Gets an Amazon Kinesis shard iterator. A shard iterator expires five minutes after it is returned to the requester.
A shard iterator specifies the shard position from which to start reading data records sequentially. The position is specified using the sequence number of a data record in a shard. A sequence number is the identifier associated with every record ingested in the stream, and is assigned when a record is put into the stream. Each stream has one or more shards.
You must specify the shard iterator type. For example, you can set the
ShardIteratorType
parameter to read exactly from the
position denoted by a specific sequence number by using the
AT_SEQUENCE_NUMBER
shard iterator type. Alternatively, the
parameter can read right after the sequence number by using the
AFTER_SEQUENCE_NUMBER
shard iterator type, using sequence
numbers returned by earlier calls to PutRecord, PutRecords,
GetRecords, or DescribeStream. In the request, you can
specify the shard iterator type AT_TIMESTAMP
to read records
from an arbitrary point in time, TRIM_HORIZON
to cause
ShardIterator
to point to the last untrimmed record in the
shard in the system (the oldest data record in the shard), or
LATEST
so that you always read the most recent data in the
shard.
When you read repeatedly from a stream, use a GetShardIterator
request to get the first shard iterator for use in your first
GetRecords request and for subsequent reads use the shard iterator
returned by the GetRecords request in
NextShardIterator
. A new shard iterator is returned by every
GetRecords request in NextShardIterator
, which you
use in the ShardIterator
parameter of the next
GetRecords request.
If a GetShardIterator request is made too often, you receive a
ProvisionedThroughputExceededException
. For more information
about throughput limits, see GetRecords, and Streams Limits in the Amazon Kinesis Data Streams Developer
Guide.
If the shard is closed, GetShardIterator returns a valid iterator for the last sequence number of the shard. A shard can be closed as a result of using SplitShard or MergeShards.
GetShardIterator has a limit of five transactions per second per account per open shard.

- If an error response is returned by Amazon
Kinesis Streams indicating either a problem with the data in
the request, or a server side issue.void increaseStreamRetentionPeriod(IncreaseStreamRetentionPeriodRequest increaseStreamRetentionPeriodRequest) throws AmazonClientException, AmazonServiceException
Increases the Kinesis data stream's retention period, which is the length of time data records are accessible after they are added to the stream. The maximum value of a stream's retention period is 168 hours (7 days).
If you choose a longer stream retention period, this operation increases the time period during which records that have not yet expired are accessible. However, it does not make previous, expired data (older than the stream's previous retention period) accessible after the operation has been called. For example, if a stream's retention period is set to 24 hours and is increased to 168 hours, any data that is older than 24 hours remains inaccessible to consumer applications.

Lists your Kinesis data streams.
The number of streams may be too large to return from a single call to
ListStreams
. You can limit the number of returned streams
using the Limit
parameter. If you do not specify a value for
the Limit
parameter, Kinesis Data Streams uses the default
limit, which is currently 10.
You can detect if there are more streams available to list by using the
HasMoreStreams
flag from the returned output. If there are
more streams available, you can request more streams by using the name of
the last stream returned by the ListStreams
request in the
ExclusiveStartStreamName
parameter in a subsequent request
to ListStreams
. The group of stream names returned by the
subsequent request is then added to the list. You can continue this
process until all the stream names have been collected in the list.
ListStreams has a limit of five transactions per second per account.

Merges two adjacent shards in a Kinesis data stream and combines them into a single shard to reduce the stream's capacity to ingest and transport data. Two shards are considered adjacent if the union of the hash key ranges for the two shards form a contiguous set with no gaps. For example, if you have two shards, one with a hash key range of 276...381 and the other with a hash key range of 382...454, then you could merge these two shards into a single shard that would have a hash key range of 276...454. After the merge, the single child shard receives data for all hash key values covered by the two parent shards.
MergeShards
is called when there is a need to reduce the
overall capacity of a stream because of excess capacity that is not being
used. You must specify the shard to be merged and the adjacent shard for
a stream. For more information about merging shards, see Merge Two Shards in the Amazon Kinesis Data Streams Developer
Guide.
If the stream is in the ACTIVE
state, you can call
MergeShards
. If a stream is in the CREATING
,
UPDATING
, or DELETING
state,
MergeShards
returns a ResourceInUseException
.
If the specified stream does not exist, MergeShards
returns
a ResourceNotFoundException
.
You can use DescribeStream to check the state of the stream, which
is returned in StreamStatus
.
MergeShards
is an asynchronous operation. Upon receiving a
MergeShards
request, Amazon Kinesis Data Streams immediately
returns a response and sets the StreamStatus
to
UPDATING
. After the operation is completed, Kinesis Data
Streams sets the StreamStatus
to ACTIVE
. Read
and write operations continue to work while the stream is in the
UPDATING
state.
You use DescribeStream to determine the shard IDs that are
specified in the MergeShards
request.
If you try to operate on too many streams in parallel using
CreateStream, DeleteStream, MergeShards
, or
SplitShard, you receive a LimitExceededException
.
MergeShards
has a limit of five transactions per second per
account.

to send data into the stream for real-time
ingestion and subsequent processing, one record at a time. Each shard can
support writes up to 1,000 records per second, up to a maximum data write
total of 1 MB per second.
You must specify the name of the stream that captures, stores, and transports the data; a partition key; and the data blob itself.
The data blob can be any type of data; for example, a segment from a log file, geographic/location data, website clickstream data, and so on.
The partition key is used by Kinesis Data Streams to distribute data across shards. Kinesis Data Streams segregates the data records that belong to a stream into multiple shards, using the partition key associated with each data record to determine the shard to which a given data record belongs.
Partition keys are Unicode strings, with a maximum length limit of 256
characters for each key. An MD5 hash function is used to map partition
keys to 128-bit integer values and to map associated data records to
shards using the hash key ranges of the shards. You can override hashing
the partition key to determine the shard by explicitly specifying a hash
value using the ExplicitHashKey
parameter. For more
information, see Adding Data to a Stream in the Amazon Kinesis Data Streams
Developer Guide.
PutRecord
returns the shard ID of where the data record was
placed and the sequence number that was assigned to the data record.
Sequence numbers increase over time and are specific to a shard within a
stream, not across all shards within a stream. To guarantee strictly
increasing ordering, write serially to a shard and use the
SequenceNumberForOrdering
parameter. For more information,
see Adding Data to a Stream in the Amazon Kinesis Data Streams
Developer Guide.
If a PutRecord
request cannot be processed because of
insufficient provisioned throughput on the shard involved in the request,
PutRecord
throws
ProvisionedThroughputExceededException
.
By default, data records are accessible for 24 hours from the time that they are added to a stream. You can use IncreaseStreamRetentionPeriod or DecreaseStreamRetentionPeriod to modify this retention period.

Kinesis Streams indicating either a problem with the data in
the request, or a server side issue.PutRecordsResult putRecords(PutRecordsRequest putRecordsRequest) throws AmazonClientException, AmazonServiceException
Writes multiple data records into a Kinesis data stream in a single call
(also referred to as a PutRecords
request). Use this
operation to send data into the stream for data ingestion and processing.
Each PutRecords
request can support up to 500 records. Each
record in the request can be as large as 1 MB, up to a limit of 5 MB for
the entire request, including partition keys. Each shard can support
writes up to 1,000 records per second, up to a maximum data write total
of 1 MB per second.
You must specify the name of the stream that captures, stores, and
transports the data; and an array of request Records
, with
each record in the array requiring a partition key and data blob. The
record size limit applies to the total size of the partition key and data
blob.
The data blob can be any type of data; for example, a segment from a log file, geographic/location data, website clickstream data, and so on.
The partition key is used by Kinesis Data Streams as input to a hash function that maps the partition key and associated data to a specific shard. An MD5 hash function is used to map partition keys to 128-bit integer values and to map associated data records to shards. As a result of this hashing mechanism, all data records with the same partition key map to the same shard within the stream. For more information, see Adding Data to a Stream in the Amazon Kinesis Data Streams Developer Guide.
Each record in the Records
array may include an optional
parameter, ExplicitHashKey
, which overrides the partition
key to shard mapping. This parameter allows a data producer to determine
explicitly the shard where the record is stored. For more information,
see Adding Multiple Records with PutRecords in the Amazon Kinesis
Data Streams Developer Guide.
The PutRecords
response includes an array of response
Records
. Each record in the response array directly
correlates with a record in the request array using natural ordering,
from the top to the bottom of the request and response. The response
Records
array always includes the same number of records as
the request array.
The response Records
array includes both successfully and
unsuccessfully processed records. Kinesis Data Streams attempts to
process all records in each PutRecords
request. A single
record failure does not stop the processing of subsequent records.
A successfully processed record includes ShardId
and
SequenceNumber
values. The ShardId
parameter
identifies the shard in the stream where the record is stored. The
SequenceNumber
parameter is an identifier assigned to the
put record, unique to all records in the stream.
An unsuccessfully processed record includes ErrorCode
and
ErrorMessage
values. ErrorCode
reflects the
type of error and can be one of the following values:
ProvisionedThroughputExceededException
or
InternalFailure
. ErrorMessage
provides more
detailed information about the
ProvisionedThroughputExceededException
exception including
the account ID, stream name, and shard ID of the record that was
throttled. For more information about partially successful responses, see
Adding Multiple Records with PutRecords in the Amazon Kinesis
Data Streams Developer Guide.
By default, data records are accessible for 24 hours from the time that they are added to a stream. You can use IncreaseStreamRetentionPeriod or DecreaseStreamRetentionPeriod to modify this retention period.

Splits a shard into two new shards in the Kinesis data stream, to
increase the stream's capacity to ingest and transport data.
SplitShard
is called when there is a need to increase the
overall capacity of a stream because of an expected increase in the
volume of data records being ingested.
You can also use SplitShard
when a shard appears to be
approaching its maximum utilization; for example, the producers sending
data into the specific shard are suddenly sending more than previously
anticipated. You can also call SplitShard
to increase stream
capacity, so that more Kinesis Data Streams applications can
simultaneously read data from the stream for real-time processing.
You must specify the shard to be split and the new hash key, which is the position in the shard where the shard gets split in two. In many cases, the new hash key might be the average of the beginning and ending hash key, but it can be any hash key value in the range being mapped into the shard. For more information, see Split a Shard in the Amazon Kinesis Data Streams Developer Guide.
You can use DescribeStream to determine the shard ID and hash key
values for the ShardToSplit
and
NewStartingHashKey
parameters that are specified in the
SplitShard
request.
SplitShard
is an asynchronous operation. Upon receiving a
SplitShard
request, Kinesis Data Streams immediately returns
a response and sets the stream status to UPDATING
. After the
operation is completed, Kinesis Data Streams sets the stream status to
ACTIVE
. Read and write operations continue to work while the
stream is in the UPDATING
state.
You can use DescribeStream
to check the status of the
stream, which is returned in StreamStatus
. If the stream is
in the ACTIVE
state, you can call SplitShard
.
If a stream is in CREATING
or UPDATING
or
DELETING
states, DescribeStream
returns a
ResourceInUseException
.
If the specified stream does not exist, DescribeStream
returns a ResourceNotFoundException
. If you try to create
more shards than are authorized for your account, you receive a
LimitExceededException
.
For the default shard limit for an AWS account, see Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To increase this limit, contact AWS Support.
If you try to operate on too many streams simultaneously using
CreateStream, DeleteStream, MergeShards, and/or
SplitShard, you receive a LimitExceededException
.
SplitShard
has a limit of five transactions per second per
account.

Enables or updates server-side encryption using an AWS KMS key for a specified stream.
Starting encryption is an asynchronous operation. Upon receiving the
request, Kinesis Data Streams returns immediately and sets the status of
the stream to UPDATING
. After the update is complete,
Kinesis Data Streams sets the status of the stream back to
ACTIVE
. Updating or applying encryption normally takes a few
seconds to complete, but it can take minutes. You can continue to read
and write data to your stream while its status is UPDATING
.
Once the status of the stream is ACTIVE
, encryption begins
for records written to the stream.
API Limits: You can successfully apply a new AWS KMS key for server-side encryption 25 times in a rolling 24-hour period.
Note: It can take up to five seconds after the stream is in an
ACTIVE
status before all records written to the stream are
encrypted. After you enable encryption, you can verify that encryption is
applied by inspecting the API response from PutRecord
or
PutRecords
.

Disables server-side encryption for a specified stream.
Stopping encryption is an asynchronous operation. Upon receiving the
request, Kinesis Data Streams returns immediately and sets the status of
the stream to UPDATING
. After the update is complete,
Kinesis Data Streams sets the status of the stream back to
ACTIVE
. Stopping encryption normally takes a few seconds to
complete, but it can take minutes. You can continue to read and write
data to your stream while its status is UPDATING
. Once the
status of the stream is ACTIVE
, records written to the
stream are no longer encrypted by Kinesis Data Streams.
API Limits: You can successfully disable server-side encryption 25 times in a rolling 24-hour period.
Note: It can take up to five seconds after the stream is in an
ACTIVE
status before all records written to the stream are
no longer subject to encryption. After you disabled encryption, you can
verify that encryption is not applied by inspecting the API response from
PutRecord

Updates the shard count of the specified stream to the specified number of shards.
Updating the shard count is an asynchronous operation. Upon receiving the
request, Kinesis Data Streams returns immediately and sets the status of
the stream to UPDATING
. After the update is complete,
Kinesis Data Streams sets the status of the stream back to
ACTIVE
. Depending on the size of the stream, the scaling
action could take a few minutes to complete. You can continue to read and
write data to your stream while its status is UPDATING
.
To update the shard count, Kinesis Data Streams performs splits or merges on individual shards. This can cause short-lived shards to be created, in addition to the final shards. We recommend that you double or halve the shard count, as this results in the fewest number of splits or merges.
This operation has the following limits. You cannot do the following:
Scale more than twice per rolling 24-hour period per stream
Scale up to more than double your current shard count for a stream
Scale down below half your current shard count for a stream
Scale up to more than 500 shards in a stream
Scale a stream with more than 500 shards down unless the result is less than 500 shards
Scale up to more than the shard limit for your account
For the default limits for an AWS account, see Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To request an increase in the call rate limit, the shard limit for this API, or your overall shard limit, use the limits form.

Creates a Kinesis data stream. A stream captures and transports data records that are continuously emitted from different data sources or producers. Scale-out within a stream is explicitly supported by means of shards, which are uniquely identified groups of data records in a stream.
You specify and control the number of shards that a stream is composed of. Each shard can support reads up to five transactions per second, up to a maximum data read total of 2 MB per second. Each shard can support writes up to 1,000 records per second, up to a maximum data write total of 1 MB per second. If the amount of data input increases or decreases, you can add or remove shards.
The stream name identifies the stream. The name is scoped to the AWS account used by the application. It is also scoped by AWS Region. That is, two streams in two different accounts can have the same name, and two streams in the same account, but in two different Regions, can have the same name.
CreateStream
is an asynchronous operation. Upon receiving a
CreateStream
request, Kinesis Data Streams immediately
returns and sets the stream status to CREATING
. After the
stream is created, Kinesis Data Streams sets the stream status to
ACTIVE
. You should perform read and write operations only on
an ACTIVE
stream.
You receive a LimitExceededException
when making a
CreateStream
request when you try to do one of the
following:
Have more than five streams in the CREATING
state at any
point in time.
Create more shards than are authorized for your account.

Deletes a Kinesis data stream and all its shards and data. You must shut
down any applications that are operating on the stream before you delete
the stream. If an application attempts to operate on a deleted stream, it
receives the exception ResourceNotFoundException
.
If the stream is in the ACTIVE
state, you can delete it.
After a DeleteStream
request, the specified stream is in the
DELETING
state until Kinesis Data Streams completes the
deletion.
Note: Kinesis Data Streams might continue to accept data read and
write operations, such as PutRecord, PutRecords, and
GetRecords, on a stream in the DELETING
state until
the stream deletion is complete.
When you delete a stream, any shards in that stream are also deleted, and any tags are dissociated from the stream.
You can use the DescribeStream operation to check the state of the

Merges two adjacent shards in a Kinesis data stream and combines them into a single shard to reduce the stream's capacity to ingest and transport data. Two shards are considered adjacent if the union of the hash key ranges for the two shards form a contiguous set with no gaps. For example, if you have two shards, one with a hash key range of 276...381 and the other with a hash key range of 382...454, then you could merge these two shards into a single shard that would have a hash key range of 276...454. After the merge, the single child shard receives data for all hash key values covered by the two parent shards.
MergeShards
is called when there is a need to reduce the
overall capacity of a stream because of excess capacity that is not being
used. You must specify the shard to be merged and the adjacent shard for
a stream. For more information about merging shards, see Merge Two Shards in the Amazon Kinesis Data Streams Developer
Guide.
If the stream is in the ACTIVE

stream is in the UPDATING
state.
You can use DescribeStream
to check the status of the
stream, which is returned in StreamStatus
. If the stream is
in the ACTIVE
state, you can call SplitShard
.
If a stream is in CREATING
or UPDATING
or
DELETING
states, DescribeStream
returns a
ResourceInUseException
.
If the specified stream does not exist, DescribeStream
returns a ResourceNotFoundException
. If you try to create
more shards than are authorized for your account, you receive a
LimitExceededException
.
For the default shard limit for an AWS account, see Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To increase this limit, contact AWS Support.
If you try to operate on too many streams simultaneously using
CreateStream, DeleteStream, MergeShards, and/or
SplitShard, you receive a LimitExceededException
.
SplitShard
has a limit of five transactions per second per
account.
streamName
- The name of the stream for the shard split.
shardToSplit
- The shard ID of the shard to split.
newStartingHashKey
-
A hash key value for the starting hash key of one of the child
shards created by the split. The hash key range for a given
shard constitutes a set of ordered contiguous positive
integers. The value for NewStartingHashKey
must
be in the range of hash keys being mapped into the shard. The
NewStartingHashKey
hash key value and all higher
hash key values in hash key range are distributed to one of
the child shards. All the lower hash key values in the range
are distributed to the other child shard.

AmazonClientException
- If any internal errors are encountered
inside the client while attempting to make the request or
handle the response. For example if a network connection is
not available.AmazonServiceException
- If an error response is returned by Amazon
Kinesis Streams indicating either a problem with the data in
the request, or a server side issue.PutRecordResult putRecord(java.lang.String streamName, java.nio.ByteBuffer data, java.lang.String partitionKey) throws AmazonClientException, AmazonServiceException
Writes a single data record into an Amazon Kinesis data stream. Call
PutRecord
to send data into the stream for real-time
ingestion and subsequent processing, one record at a time. Each shard can
support writes up to 1,000 records per second, up to a maximum data write
total of 1 MB per second.
You must specify the name of the stream that captures, stores, and transports the data; a partition key; and the data blob itself.
The data blob can be any type of data; for example, a segment from a log file, geographic/location data, website clickstream data, and so on.
The partition key is used by Kinesis Data Streams to distribute data across shards. Kinesis Data Streams segregates the data records that belong to a stream into multiple shards, using the partition key associated with each data record to determine the shard to which a given data record belongs.
Partition keys are Unicode strings, with a maximum length limit of 256
characters for each key. An MD5 hash function is used to map partition
keys to 128-bit integer values and to map associated data records to
shards using the hash key ranges of the shards. You can override hashing
the partition key to determine the shard by explicitly specifying a hash
value using the ExplicitHashKey
parameter. For more
information, see Adding Data to a Stream in the Amazon Kinesis Data Streams
Developer Guide.
PutRecord
returns the shard ID of where the data record was
placed and the sequence number that was assigned to the data record.
Sequence numbers increase over time and are specific to a shard within a
stream, not across all shards within a stream. To guarantee strictly
increasing ordering, write serially to a shard and use the
SequenceNumberForOrdering
parameter. For more information,
see Adding Data to a Stream in the Amazon Kinesis Data Streams
Developer Guide.
If a PutRecord
request cannot be processed because of
insufficient provisioned throughput on the shard involved in the request,
PutRecord
throws
ProvisionedThroughputExceededException
.
By default, data records are accessible for 24 hours from the time that they are added to a stream. You can use IncreaseStreamRetentionPeriod or DecreaseStreamRetentionPeriod to modify this retention period.
streamName
- The name of the stream to put the data record into.
data
- The data blob to put into the record, which is base64-encoded when the blob is serialized. When the data blob (the payload before base64-encoding) is added to the partition key size, the total size must not exceed the maximum record size (1 MB).
partitionKey
- Determines which shard in the stream the data record is assigned to. Partition keys are Unicode strings with a maximum length limit of 256 characters for each key. Amazon Kinesis Data Streams uses the partition key as input to a hash function that maps the partition key and associated data to a specific shard. Specifically, an MD5 hash function is used to map partition keys to 128-bit integer values and to map associated data records to shards. As a result of this hashing mechanism, all data records with the same partition key map to the same shard within the stream.

Kinesis Streams indicating either a problem with the data in

Gets an Amazon Kinesis shard iterator. A shard iterator expires five minutes after it is returned to the requester.
A shard iterator specifies the shard position from which to start reading data records sequentially. The position is specified using the sequence number of a data record in a shard. A sequence number is the identifier associated with every record ingested in the stream, and is assigned when a record is put into the stream. Each stream has one or more shards.
You must specify the shard iterator type. For example, you can set the
ShardIteratorType
parameter to read exactly from the
position denoted by a specific sequence number by using the
AT_SEQUENCE_NUMBER
shard iterator type. Alternatively, the
parameter can read right after the sequence number by using the
AFTER_SEQUENCE_NUMBER
shard iterator type, using sequence
numbers returned by earlier calls to PutRecord, PutRecords,
GetRecords, or DescribeStream. In the request, you can
specify the shard iterator type AT_TIMESTAMP
to read records
from an arbitrary point in time, TRIM_HORIZON
to cause
ShardIterator
to point to the last untrimmed record in the
shard in the system (the oldest data record in the shard), or
LATEST
so that you always read the most recent data in the
shard.
When you read repeatedly from a stream, use a GetShardIterator
request to get the first shard iterator for use in your first
GetRecords request and for subsequent reads use the shard iterator
returned by the GetRecords request in
NextShardIterator
. A new shard iterator is returned by every
GetRecords request in NextShardIterator
, which you
use in the ShardIterator
parameter of the next
GetRecords request.
If a GetShardIterator request is made too often, you receive a
ProvisionedThroughputExceededException
. For more information
about throughput limits, see GetRecords, and Streams Limits in the Amazon Kinesis Data Streams Developer
Guide.
If the shard is closed, GetShardIterator returns a valid iterator for the last sequence number of the shard. A shard can be closed as a result of using SplitShard or MergeShards.
GetShardIterator has a limit of five transactions per second per account per open shard.
