AWSLambdaUpdateEventSourceMappingRequest

Objective-C

@interface AWSLambdaUpdateEventSourceMappingRequest

Swift

class AWSLambdaUpdateEventSourceMappingRequest

  • The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

    • Amazon Kinesis - Default 100. Max 10,000.

    • Amazon DynamoDB Streams - Default 100. Max 10,000.

    • Amazon Simple Queue Service - Default 10. For standard queues the max is 10,000. For FIFO queues the max is 10.

    • Amazon Managed Streaming for Apache Kafka - Default 100. Max 10,000.

    • Self-Managed Apache Kafka - Default 100. Max 10,000.

    • Amazon MQ (ActiveMQ and RabbitMQ) - Default 100. Max 10,000.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable batchSize;

    Swift

    var batchSize: NSNumber? { get set }

  • (Streams only) If the function returns an error, split the batch in two and retry.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable bisectBatchOnFunctionError;

    Swift

    var bisectBatchOnFunctionError: NSNumber? { get set }

  • (Streams only) An Amazon SQS queue or Amazon SNS topic destination for discarded records.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSLambdaDestinationConfig *_Nullable destinationConfig;

    Swift

    var destinationConfig: AWSLambdaDestinationConfig? { get set }

  • When true, the event source mapping is active. When false, Lambda pauses polling and invocation.

    Default: True

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable enabled;

    Swift

    var enabled: NSNumber? { get set }

  • (Streams and Amazon SQS) An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSLambdaFilterCriteria *_Nullable filterCriteria;

    Swift

    var filterCriteria: AWSLambdaFilterCriteria? { get set }

  • The name of the Lambda function.

    Name formats

    • Function name - MyFunction.

    • Function ARN - arn:aws:lambda:us-west-2:123456789012:function:MyFunction.

    • Version or Alias ARN - arn:aws:lambda:us-west-2:123456789012:function:MyFunction:PROD.

    • Partial ARN - 123456789012:function:MyFunction.

    The length constraint applies only to the full ARN. If you specify only the function name, it’s limited to 64 characters in length.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable functionName;

    Swift

    var functionName: String? { get set }

  • (Streams and Amazon SQS) A list of current response type enums applied to the event source mapping.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSArray<NSString *> *_Nullable functionResponseTypes;

    Swift

    var functionResponseTypes: [String]? { get set }

  • (Streams and Amazon SQS standard queues) The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function.

    Default: 0

    Related setting: When you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable maximumBatchingWindowInSeconds;

    Swift

    var maximumBatchingWindowInSeconds: NSNumber? { get set }

  • (Streams only) Discard records older than the specified age. The default value is infinite (-1).

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable maximumRecordAgeInSeconds;

    Swift

    var maximumRecordAgeInSeconds: NSNumber? { get set }

  • (Streams only) Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records will be retried until the record expires.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable maximumRetryAttempts;

    Swift

    var maximumRetryAttempts: NSNumber? { get set }

  • (Streams only) The number of batches to process from each shard concurrently.
