> Currently the DescribeStream AWS API used to get list of shards is has a restricted rate limits on AWS. (5 requests per sec per account). This is problematic when running multiple flink jobs all on same account since each subtasks calls the Describe Stream. Changing this to ListShards will provide more flexibility on rate limits as ListShards has a 100 requests per second per data stream limits.
