Crash when adding node to cluster with big journal on PSQL DB
-------------------------------------------------------------
Key: JCR-2832
URL: https://issues.apache.org/jira/browse/JCR-2832
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: clustering, jackrabbit-core
Affects Versions: 2.1.2
Environment: Clustering with database journal using PSQL
Reporter: Omid Milani
Fix For: 2.1.3
When adding a new node to a cluster with big journal on PSQL database
application runs out of memory on the new node and crashes (no exception,
application exits with code 137).
It's because with PSQL, when no fetchSize is specified, all the results of
query are loaded into memory before being passed to application. Furthermore,
specification of fetchSize only works in transactional mode and have no effect
if autoCommit is true. (these are configured in ConnectionHelper)
