Description of problem:

When using AWS provisioned DynamoDB, the microservice orders-events-consumer is not always fetching DynamoDB events properly.

DynamoStreams service exposes a non-trivial interface for fetching DynamoDB events.
To read events you must connect to the Streams exposed by DynamoStreams. Each stream contains one or more of Shards of events. The number of Streams, and Shards for each Stream can vary in time.

To remediate, implement this component as Labmda function
