While I myself work exclusively with CQ in production, I know for a fact that many use Sling+JCR in production. Not sure what you mean by 'released in a production ready incarnation' though. If you are looking for a launchpad release, people typically build their own launchpads, based on their needs. I personally would start with the latest SNAPSHOT launchpad and customise it for my needs. > > 2.

Derby is also used as the default persistence engine for Jackrabbit. > ./launchpad/testing/target/launchpad-bundles/resources/bundles.oak/15: > guava-15.0.jar oak-blob-1.0.0.jar > oak-commons-1.0.0.jar oak-core-1.0.0.jar oak-lucene-1.0.0.jar > oak-mk-1.0.0.jar oak-mk-api-1.0.0.jar oak-mk-remote-1.0.0.jar > org.apache.sling.jcr.oak.server-0.0.2-SNAPSHOT.jar These are the oak jars.

Note that the two directories you mentioned are specific to different run modes: - 'bundles.jackrabbit' -> jackrabbit run mode ( default ) - 'bundles.oak' -> oak So they won't run at the same time, and by default you get Jackrabbit 2.x . > How does https://github.com/apache/jackrabbit-oak.git fit into sling/trunk? > > Or, does one need to use the sling-oak-it-1.7 build, (SLING-2788) to use > oak as the JCR? See above, we include the jars into the launchpad in the oak run mode. You need to use -Dsling.run.modes=oak to choose Oak [1]. But that's not working perfectly yet, which is why we excluded it from the Sling 7 release. > 3. Can sling be configured to use the S3DataStore BloblStore back end? > This is a requirement for us.

For Jackrabbit 2.x you can create the sling/jackrabbit/repository.xml file before starting Sling for the first time [2] and it will use your configuration instead of the default one.
