----------------------------------
Summary: Provide option to set query memory as percent of total
Key: DRILL-5815
URL: https://issues.apache.org/jira/browse/DRILL-5815
Project: Apache Drill
Issue Type: Improvement
Affects Versions: 1.11.0
Reporter: Paul Rogers
Assignee: Paul Rogers
Fix For: 1.12.0
Drill provides a parameter to set the memory per query as a static number which
defaults to 2 GB. This number is a wonderful setting for the default Drillbit
configuration of 8 GB heap; it allows 2-3 concurrent queries. But, as Drillbit
memory increases, the default becomes a bit constraining. While users can
change the setting, they seldom do.
In addition, provide an option that sets memory as a percent of total memory.
If the allocation is 10%, say, and total memory is 128 GB, then each query gets
~13GB, which is a big improvement.
The existing option acts as a floor: the query must receive at least that much
memory.
