Netty thread pool count configurable)
> Make JM REST Netty thread pool count configurable
> -------------------------------------------------
>
> Key: FLINK-23321
> URL: https://issues.apache.org/jira/browse/FLINK-23321
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Metrics, Runtime / REST
> Reporter: Nicolas Raga
> Priority: Minor
> Labels: Monitoring, Netty, REST
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> Currently
> [rest.server.numThreads|https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/deployment/config/#rest-server-numthreads]
> works to create more DispatcherRestEndpoint threads which help in high usage
> of functionality in the purview of job the dispatcher functionality. However,
> we cannot tune the number of netty threads use to handle incoming
> connections. Especially when using the REST server as a monitoring endpoint,
> a lack of netty threads cause connection times and a long lags in responses.
>
> Such configuration already exists for taskmanagers
> (*taskmanager.network.netty.client/server.numThreads*) and such
> implementation of a *server.netty-boss.numThreads* and
> *server.netty-worker.numThreads* would be of great use.
