    • 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.
