Consider replacing homegrown XML-Relational doc cache implementation with JBoss Cache or other standard implementation ---------------------------------------------------------------------------------------------------------------------- Key: TEIID-128 URL: https://jira.jboss.org/jira/browse/TEIID-128 Project: Teiid Issue Type: Quality Risk Components: XML Connector Affects Versions: 6.x Reporter: Greg Haber Priority: Minor Fix For: 6.1.0 My understanding is that the document cache implementation in the XML-Relational connector is a homegrown implementation. Homegrown = more code to maintain and better chance of us hitting major issues like JBEDSP-834. Plus AFAIK this homegrown cache implementation locks the whole cache even on read operations which I suspect is going to introduce scaling problems (in fact I think we actually experienced this at a customer with 5.0SP2 but we were unable to conclusively determine that that was the cause of problems we saw then).
