[jboss-jira] [JBoss JIRA] (WFLY-6332) HHH-10563: Significant String use/duplication associated with subselect fetch
[
https://issues.jboss.org/browse/WFLY-6332?page=com.atlassian.jira.plugin....
]
Stephen Fikes updated WFLY-6332:
--------------------------------
Description: The use of @Fetch(FetchMode.SUBSELECT) results in a significant level of
string duplication for SQL and SQL fragments. When loading large datasets and/or higher
numbers of associations with multiple associations using SUBSELECT the memory can
accumulate significantly (e.g. on the order of multiple GB for string space associated
with the duplicate SQL fragments alone).
