---------------------------------
Summary: Increase the default value of
partitioner_sender_threads_factor
Key: DRILL-2809
URL: https://issues.apache.org/jira/browse/DRILL-2809
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Affects Versions: 0.8.0
Reporter: Aman Sinha
Assignee: Aman Sinha
The current default value of planner.partitioner_sender_threads_factor is 1.
This is too low for most requirements. In one scenario the elapsed time of a
query on a 20 node cluster went from 158 secs to 60 secs when increasing the
value to 2. However, we have to determine a reasonable default for this and
related partition_sender settings.
