------------------------------------
Summary: Make the objectstore-secondary connection pool size
configurable
Key: HIVE-28900
URL: https://issues.apache.org/jira/browse/HIVE-28900
Project: Hive
Issue Type: Improvement
Affects Versions: 4.0.1
Reporter: Miklos Szurap
Assignee: Miklos Szurap
The secondary connection factory is used for schema generation, and for value
generation operations. Under normal circumstances 2 connections should be
sufficient, however, we have found in HIVE-28839 that connection starvation may
still happen. (in that case due to a datanucleus bug)
We should make the "objectstore-secondary" pool size configurable. This is
needed at least until a final fix is not available for HIVE-28839, but probably
it is good to have on the long run if we find other edge cases too.
