Amazon API Gateway increased REST API execution log event size from 1 KB to 1 MB, allowing more detailed request and response data capture. Additionally, it introduced configurable delivery destinations enabling logs to be routed simultaneously to multiple targets such as customer-managed Amazon CloudWatch Logs groups, S3 buckets, or Kinesis Data Firehose streams. This flexibility supports use cases like long-term log storage in Apache Parquet format on S3 with query capability in Athena, alongside real-time alerting via CloudWatch Logs.
This capability is a provisioned enhancement fully deployed in all supported AWS Regions, including GovCloud. It requires client configuration via console, CLI, or CloudFormation and charges according to CloudWatch Logs vended log rates. The feature improves operational visibility by overcoming previous truncation and fixed destination limitations.
