[overlord-issues] [JBoss JIRA] (ARTIF-689) Remove the JCR persistence adapter

Remove the JCR persistence adapter ---------------------------------- Key: ARTIF-689 URL: https://issues.jboss.org/browse/ARTIF-689 Project: Artificer Issue Type: Task Reporter: Brett Meyer Assignee: Brett Meyer Fix For: 1.1.0.Final, 1.0.0.Beta1 ARTIF-683 switched to a JPA/RDBMS default persistence strategy. Originally, we intended to keep the JCR plugin and continue to maintain it, however: First and foremost, initial performance tests are looking extremely promising. With the exception of uploads (slower for JPA due to Hibernate Search indexing and complicated INSERTs, as opposed to JCR node creation), everything else is 2-5x faster, including complex queries. Further, I'm starting to hit certain dependency conflicts between Hibernate and ModeShape that might eventually require a split in Artificer distros. Maintaining both is already becoming a headache. Is there much of a point in keeping both? The only argument I can think of is if for some reason a user was integrating S-RAMP's JCR storage with their existing, *non-RDBMS* source (Cassandra, etc) through ModeShape/Infinispan. But that's highly unlikely. In my mind, everything else trumps the off-chance for backward compatibility issues. Most users we talk to see JCR purely as an implementation detail. We will, however, provide a migration strategy. It would simply be code fragments from both adapters, translating to and from the backends. Honestly simple stuff.
