API Gateway Async Lambda Invocation

[akshitkh]

Describe the feature

This feature allows users to build an API Gateway with an asynchronous Lambda integration, in addition to a DynamoDB integration. The POST method submits an async request to Lambda, and returns a jobID to the user.

The user can then use the GET method to query the jobStatus for that jobId. The GET method relies on direct DynamoDB integration with API Gateway.

Use Case

Giving users the ability to receive a jobId for an async invocation, thus allowing them to check the jobStatus for that jobId.

Proposed Solution

I am using API Gateway context to return a requestId upon a POST request. The Lambda function stores this requestId in the DynamoDB table.

The GET method queries the DynamoDB table for that requestId, and returns the value of the status attribute.
