----------------------------------
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.
