Hi Sling users, FYI the Oak team just announced a hackathon in Basel, August 21-25.
I'm relaying the info here as Sling users might be interested in contributing to our storage layers or better understanding how they work. Please ask any specific questions on the oak-dev list. See https://wiki.apache.org/jackrabbit/Oakathon%20August%202017 and https://lists.apache.org/thread.html/c973fbe36b02f3be658c543679c123a9d7525a0c390d828b83ce13ab@%3Coak-dev.jackrabbit.apache.org%3E -Bertrand
