Subject [jira] [Created] (PHOENIX-5495) Avoid server-server RPCs when row locks are held inside MetaDataEndpointImpl
Date Fri, 27 Sep 2019 00:21:00 GMT
Chinmay Kulkarni created PHOENIX-5495:
-----------------------------------------

             Summary: Avoid server-server RPCs when row locks are held inside MetaDataEndpointImpl
                 Key: PHOENIX-5495
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5495
             Project: Phoenix
          Issue Type: Improvement
    Affects Versions: 4.15.0, 5.1.0
            Reporter: Chinmay Kulkarni
             Fix For: 4.15.1, 5.1.1


At various spots in MetaDataEndpointImpl, we acquire row locks and then while locks are held,
do server-to-server RPC calls. This can lead to lock starvation if RPCs take too long. We
should decouple such interactions as much as possible.
