[jira] [Created] (PHOENIX-5045) Remove Global Mutable index code from Phoenix

Lars Hofhansl created PHOENIX-5045:
--------------------------------------

             Summary: Remove Global Mutable index code from Phoenix
                 Key: PHOENIX-5045
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5045
             Project: Phoenix
          Issue Type: Task
            Reporter: Lars Hofhansl


In a continued effort to reduce Phoenix' complexity I propose that we remove the current GLOBAL MUTABLE index implementation from Phoenix.

It can't be made working reliably and comes with considerable complexity such as:
* temporarily disabled indexes, or
* indexes that return stale data, and
* complex catch-up logic
* server-to-server communication with the risk of tying up handler threads

IMHO it does not even matter whether we have a replacement or not. The current code should not be used.

Let's discuss.
