             Summary: Remove extraneous operations during upsert with local immutable index
                 Key: PHOENIX-3128
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3128
             Project: Phoenix
          Issue Type: Bug
            Reporter: Junegunn Choi
            Assignee: Junegunn Choi


Upsert to a table with a local immutable index is supposed to be more efficient than to a table with a local mutable index, but it's actually slower (in our environment by 30%) due to extraneous operations involved.

The problem is twofold:

1. Client unnecessarily prepares and sends index update.
2. Index cleanup is done regardless of the immutability of the table.
