Summary: increase LLAP IO queue size for perf
Key: HIVE-19875
URL: https://issues.apache.org/jira/browse/HIVE-19875
Project: Hive
Issue Type: Bug
Affects Versions: 3.1.0, 4.0.0
Reporter: Prasanth Jayachandran
Assignee: Prasanth Jayachandran
According to [~gopalv] queue limit has perf impact, esp. during hashtable load
for mapjoin where in the past IO used to queue up more data for processing to
process.
1) Overall the default limit could be adjusted higher.
2) Depending on Decimal64 availability, the weight for decimal columns could be
reduced.
