Summary: Early EndDataStream RPC could be responded earlier Key: IMPALA-12968 URL: https://issues.apache.org/jira/browse/IMPALA-12968 Project: IMPALA Issue Type: Improvement Components: Backend Reporter: Csaba Ringhofer When a producer fragment sends no rows and finishes before the receiver is initialized te e EndDataStream rpc is stored as early sender and is responded when the receiver is registered. [https://github.com/apache/impala/blob/effc9df933b46eb5b0acf55a858606415425505f/be/src/runtime/krpc-data-stream-mgr.cc#L150] While it is important to store the information that the EOS has happened to unregister the sender from the receiver, the RPC itself could be responded right after it was stored in the early sender map. -- This message was sent by Atlassian Jira (v8.20.10#820010)
