----------------------------------------
Summary: Consider removing RpcService#getExecutor
Key: FLINK-21368
URL: https://issues.apache.org/jira/browse/FLINK-21368
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Reporter: Chesnay Schepler
Fix For: 1.13.0
{{RpcService#getExecutor}} exposes Akka's underlying dispatcher thread which
introduces the risk of the thread being blocking by an IO operation of another
component.
We should look into removing this method, and migrate existing usages to either
a dedicated executor or explicitly passing the main thread executor if required.
