[jira] [Created] (FLINK-3120) Set number of event loop thread and
number of buffer pool arenas to same number
Ufuk Celebi created FLINK-3120:
----------------------------------
Summary: Set number of event loop thread and number of buffer pool arenas to same number
Key: FLINK-3120
URL: https://issues.apache.org/jira/browse/FLINK-3120
Project: Flink
Issue Type: Improvement
Components: Distributed Runtime
Affects Versions: 0.10.1
Reporter: Ufuk Celebi
Assignee: Ufuk Celebi
Fix For: 0.10.2
If a user changes the default number of event loop threads, the number of buffer pool arenas is still the default (2 * cores). Both numbers should be the same to prevent buffer allocation contention during runtime.
