> Key: FLINK-17970
> URL: https://issues.apache.org/jira/browse/FLINK-17970
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Affects Versions: 1.11.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.11.0
>
>
> Currently, the default value of {{ClusterOptions.CLUSTER_IO_EXECUTOR_POOL_SIZE}} is #cores. I propose to increase it to 4 * #cores to support a higher load of blocking IO operations.
> Moreover, I propose to use a cached thread pool instead of a fixed thread pool. That way, only those use cases which have high IO load will actually occupy the required resources to start more threads.
> Last but not least, I propose to change the config option name from {{cluster.io-executor.pool-size}} to {{cluster.io-pool.size}} which is a bit shorter.
