[jira] [Created] (PHOENIX-4762) Performance regression with transactional immutable indexes

James Taylor created PHOENIX-4762:
-------------------------------------

             Summary: Performance regression with transactional immutable indexes
                 Key: PHOENIX-4762
                 URL: https://issues.apache.org/jira/browse/PHOENIX-4762
             Project: Phoenix
          Issue Type: Bug
            Reporter: James Taylor
            Assignee: James Taylor


The introduction of the TAL caused a performance regression with immutable indexes. Prior to the TAL, index rows would not be transaction participants so they would not take up client memory. Instead, on rollback, we re-generate the index deletes.
