AWS AppSync now supports long running events with asynchronous Lambda function invocations
News
AWS AppSync now supports invoking Lambda functions asynchronously (in Event mode) in addition to the existing synchronous mode. This enables long-running operations, batch processing, and scenarios where immediate responses are not required.
Specifically, the article covers:
- AWS AppSync now allows event-driven, asynchronous invocation of Lambda functions configured as data sources
- Previously, Lambda functions could only be invoked synchronously, blocking the API response until Lambda execution completed
- The new Event mode decouples the API response from Lambda execution, enabling long-running operations, batch processing, and use cases without needing immediate responses
- This feature is available in all AWS regions supported by AppSync
