[jira] [Created] (IMPALA-10860) Allow setting separate mem_limit
for coordinators and executors
Abhishek Rawat created IMPALA-10860:
---------------------------------------
Summary: Allow setting separate mem_limit for coordinators and executors
Key: IMPALA-10860
URL: https://issues.apache.org/jira/browse/IMPALA-10860
Project: IMPALA
Issue Type: Task
Reporter: Abhishek Rawat
Assignee: Abhishek Rawat
The mem_limit query option applies to all impala coordinators and executors. This may not be ideal for dedicated coordinators, since they generally need less memory per query and having same memory limit will reduce system wide query concurrency.
We could add new query options:
{code:java}
mem_limit_coordinators
mem_limit_executors
{code}
