How to retrieve a shard ID of DynamoDB in Lambda functions?

AWS DynamoDB Triggers enable us to capture all changes in our DynamoDB table. Lambda assigns each Lambda function to a shard of DynamoDB Streams.

I want to retrieve a shard ID in Lambda function to keep consistency in some data processing tasks, but I can't find the way to get it. Does any one manage to do it?

AWS Lambda abstracts the details of shard processing and serialization away from you. The only way to process a stream and be aware of the shard ID at the same time is to consume the stream yourself using the KCL and the DynamoDB Streams adapter.
