-------------------------------------
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.
