[jira] [Created] (OPENJPA-2249) Minor performance improvement when
using LiteAutoDetach
Rick Curtis created OPENJPA-2249:
------------------------------------
Summary: Minor performance improvement when using LiteAutoDetach
Key: OPENJPA-2249
URL: https://issues.apache.org/jira/browse/OPENJPA-2249
Project: OpenJPA
Issue Type: Improvement
Components: kernel, performance
Affects Versions: 2.2.0, 2.3.0
Reporter: Rick Curtis
Priority: Minor
Fix For: 2.3.0
I have found that when detaching the entire persistence context we create a new collection of all items that need to be detached but we could be smarter and just create an intelligent iterator. This new iterator will iterate over each collection/map that needs to be detached.
In local perf testing this showed a marginal improvement.
