[jira] [Created] (PHOENIX-5131) Make spilling to disk for
order/group by configurable
Abhishek Singh Chouhan created PHOENIX-5131:
-----------------------------------------------
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.
