From Craig L Russell <Craig.Russ...@Sun.COM>
Subject Minutes: JDO TCK Conference Call Friday, July 11, 9 am PDT
Date Fri, 11 Jul 2008 16:48:02 GMT
Attendees: Michelle Caisse, Richard Schilling, Craig Russell


1. L2 Caching extension. Andy proposes a simple extension to annotate/ 
metadate classes and fields to be cacheable or not. Seems easy enough  
and no other implications except the addition of new annotation class  
@Cacheable and xml element cacheable. Comments? Post replies to Andy's  
email. AI Andy make a JIRA.

2. Other issues.

Richard has a patch for https://issues.apache.org/jira/browse/JDO-582.  
He will upload a patch this week end.

Working on https://issues.apache.org/jira/browse/JDO-555 it seems that  
DataNucleus and or c3p0 need some non-trivial entries.

An interesting option for a JDO implementation is to use a RESTful  
service like Amazon S3 or memcached for the back end. Some obvious  
issues are transactions, object identity, and query. But having an  
object front end for these would have clear productivity benefits  
compared to a user writing the entire thing by hand (tools are pretty  
simple for accessing data from these services).

Action Items from weeks past:

[Jun 20  2008] AI: Craig reply to Joerg regarding bidirectional  
relationships and possibly update the spec to include the rationale.

[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.
