[jira] [Created] (FLINK-10718) Use IO executor in RpcService for
message serialization
Till Rohrmann created FLINK-10718:
-------------------------------------
Summary: Use IO executor in RpcService for message serialization
Key: FLINK-10718
URL: https://issues.apache.org/jira/browse/FLINK-10718
Project: Flink
Issue Type: Improvement
Components: Local Runtime
Affects Versions: 1.6.2, 1.5.5, 1.7.0
Reporter: Till Rohrmann
Fix For: 1.7.0
The {{AkkaInvocationHandler}} and once FLINK-10251 has been merged also the {{AkkaRpcActor}} serialize their remote RPC messages before sending them. This happens in the calling thread which can be a main thread of another {{RpcEndpoint}}. Depending on the de-/serialization time, this can be considered a blocking operation. Thus, I propose to introduce an IO executor which is being used for the serialization of the messages. This will make the {{RpcService}} abstraction more scalable.
