             Summary: Connection throttling doesn't always decrement on connection close
                 Key: PHOENIX-3877
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3877
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.10.0
            Reporter: Geoffrey Jacoby
            Assignee: Geoffrey Jacoby


PHOENIX-3663 introduced optional connection throttling in the JDBC driver. While the throttling itself works properly, the decrement operation on connection close won't update the open connection count unless an unrelated setting, returnSequenceValues, is true. (This is because the connection counts were originally built for sequence logic.) The result is that once we throttle, we often can't un-throttle even after congestion abates.  

The decrement operation on connection close should also take place anytime the connection throttling is turned on.
