Topic / Discussion Points / Action Items
·  Performance issues and lockups with lexevsapi (Systems/Tracy) / May be issued caused as more users migrating to 4.2. However, not sure where issue is getting created. Users sometimes experience up to 10 minutes of down time. (30 minutes max has been experienced). Access to the stats is available in note from Chet. Contact Norval and Chet with questions. / Kevin will take a look at available logs and will work with Norval and Chet.
·  Performance Issues (Kevin) / Mayo has begun looking at optimizing for use cases presented by the browser team. Considerations to the Lucene code - we have updated to new versions of lucene; Updated the jars, but have left code the same in past releases, so now time to review the code. Primary usecase we are considering - browser to display first 50-100 results of top ranked query results. Investigating possibilities - Optimize lucene code, lazy loading, general mysql tweaks (joins vs sep selects). Next going to look at graph performance. No performance timings current exist, but in next week will attempt to show some results.
·  Backwards Compatibility (5.0, 4.2) / For example, load content with 4.2 and can you use the 5.1 jar with that content? It was stated that when we go across major release boundary, do not require this compatibility.
·  Loader Framework - Metadata Loader requirements (Scott) / Metadata loading is optional during load. However, as we move to the new loader framework, may need to re-implement the metadata loader in the framework. Other options exist for possible consideration in the future. / Plan on discussing future options when Gilberto is available. Include Pradip.
For 5.1 release we will still load metadata as currently implemented.
· 
Adjourn / Thanks for your participation!
