Attendees: Michael Bouschen, Craig Russell Agenda:
1. Support for streams https://issues.apache.org/jira/browse/JDO-625 Seems like a good idea. Any implementation issues? Should we add an optional feature flag or make it required?Should we restrict use of the PersistenceManager (including accessing unloaded fields of the same or other instances managed by the same PersistenceManager) while the user is reading the stream?
2. Query behaviour independent of transactional boundaries https://issues.apache.org/jira/browse/JDO-624 .
Seems reasonable to have a flag that mandates the behavior of query after commit. It's not generally good for the HOLD_CURSORS_OVER_COMMIT flag to be set in a query, since it requires that the Connection be held by the PersistenceManager for longer than it otherwise would be.
Where would the flag go? Query? Transaction? PersistenceManager? PersistenceManagerFactory? Where to get defaults?
Should the feature be optional or required?Also need to specify the behavior of the Query results so the user can close them explicitly when done. Otherwise, closing the PersistenceManager would close the Query (currently not specified, but implied).
