Attendees: Richard Schilling, Michelle Caisse, Craig Russell
Agenda:
1. Control over transaction isolation level. There does not appear to
be agreement over whether it is possible to completely define
transactional behavior of a jdo implementation. While it is possible
for the implementation to use a user-specified transaction isolation
level for the underlying datastore, it's still not possible to mandate
the behavior associated with, e.g., read-uncommitted.
2. Other issues
Richard downloaded Grails and was impressed. The separation of
persistence specification from the actual class was not so great, but
the overall experience was excellent.
Release schedule for JDO 2.2. Looks like most of the issues can be
done by end of September, so let's try for at least a preview by then.
The last release was done in March, so six month schedule would have a
new release in September. There are some JCP gating processes so we
should try to close on the specification issues soon.
Re: https://issues.apache.org/jira/browse/JDO-556 assigned temporarily
to Craig to add a requirement for a no-args constructor for PMF as a
prerequisite for ServiceLoader.
Action Items from weeks past:
[Feb 1 2008] AI Matthew see what would be needed to update the PMF
contract to support ServiceLoader.
[Nov 30 2007] AI Christiaan propose more details on Update/copy by
query for post-JDO 2.1.
[May 25 2007] AI everyone download the Grails demo from grails.org
and check it out. Also look at Grails/Groovy ExpandoMetaClass that
has the magic to avoid reflection and enhancement.
[May 25 2007] AI Matthew Adams prepare a proposal with just the basics
of schema synchronization with jdo and orm metadata.
[Aug 11 2006] AI Craig propose some semantics for behavior if user
tries to add to a list where the ordering element is incorrect.
[Sep 2 2005] AI: To recruit members: Articles on TheServerSide
directing attention to the site. T-shirts. AI: Craig write a
ServerSide article.
