             Summary: Make spilling to disk for order/group by configurable
                 Key: PHOENIX-5131
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5131
             Project: Phoenix
          Issue Type: Improvement
            Reporter: Abhishek Singh Chouhan
            Assignee: Abhishek Singh Chouhan


We've observed that large queries, doing order/group by leading to issues on the regionserver
(crashes/long gc pauses/file handler exhaustion etc.). We should make spilling to disk configurable
and in case its disabled, fail the query once it hits the spilling limit on any of the region
servers. Also make spooling threshold server-side property only to prevent clients from controlling
memory allocation on the rs side.
