> *Background*
> The Amazon Kinesis Data Streams consumer supports consuming from Amazon DynamoDB via the [DynamoDB Streams Kinesis Adapter|https://github.com/awslabs/dynamodb-streams-kinesis-adapter]. 
> *Problem*
> We have seen instances of consumer throwing {{ResouceNotFoundException}} when attempting to invoke {{GetShardIterator}}.
> {code}
> com.amazonaws.services.kinesis.model.ResourceNotFoundException: Requested resource not found: Shard does not exist 
> {code}
> According to the DynamoDB team, the {{DescribeStream}} call may return shard IDs that are no longer valid, and this exception needs to be handled by the client. 
> *Solution*
> Modify the DynamoDB consumer to treat {{ResourceNotFoundException}} as a shard closed signal.
