> FlinkKinesisConsumer does not balance shards over subtasks
> ----------------------------------------------------------
>
> Key: FLINK-8516
> URL: https://issues.apache.org/jira/browse/FLINK-8516
> Project: Flink
> Issue Type: Bug
> Components: Kinesis Connector
> Affects Versions: 1.4.0, 1.3.2, 1.5.0
> Reporter: Thomas Weise
> Priority: Major
>
> The hash code of the shard is used to distribute discovered shards over
> subtasks round robin. This works as long as shard identifiers are sequential.
> After shards are rebalanced in Kinesis, that may no longer be the case and
> the distribution become skewed.
