[jira] [Commented] (FLINK-4382) Buffer rpc calls until RpcEndpoint is properly started

["Stephan Ewen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-4382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15417432#comment-15417432 ] 

Stephan Ewen commented on FLINK-4382:
-------------------------------------

Would it buffer the messages, or simply discard them while the endpoint is not ready?
I think discarding is fine. It would be equivalent to the behavior that the endpoint started later (was unavailable for some time), which all senders have to be able to deal with anyways.

> When creating a {{RpcEndpoint}} it starts a rpc server. The server should wait to dispatch incoming rpc calls until the {{RpcEndpoint}} signals that it's ready.
