[jira] [Created] (FLINK-8944) Use ListShards for shard discovery in the flink kinesis connector

----------------------------------------------

             Summary: Use ListShards for shard discovery in the flink kinesis connector
                 Key: FLINK-8944
                 URL: https://issues.apache.org/jira/browse/FLINK-8944
             Project: Flink
          Issue Type: Improvement
            Reporter: Kailash Hassan Dayanand


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.
