             Summary: Further enhance adaptiveReads in Kinesis Connector to read more records in the case of long running loops
                 Key: FLINK-9897
                 URL: https://issues.apache.org/jira/browse/FLINK-9897
             Project: Flink
          Issue Type: Improvement
          Components: Kinesis Connector
            Reporter: Lakshmi Rao


In FLINK-9692, we introduced the ability for the shardConsumer to adaptively read more records based on the current average record size to optimize the 2 Mb/sec shard limit. The feature maximizes  maxNumberOfRecordsPerFetch of 5 reads/sec (as prescribed by Kinesis limits). In the case where applications take more time to process records in the run loop, they are no longer able to read at a frequency of 5 reads/sec (even though their fetchIntervalMillis maybe set to 200 ms). In such a scenario, the maxNumberOfRecordsPerFetch should be calculated based on the time that the run loop actually takes as opposed to fetchIntervalMillis.
