Hi, One of the things I need to implement for MongoMK is BlobStore garbage collection. I see that there's an initial implementation for garbage collection in AbstractBlobStore in oak-mk and I also see this bug [0] to improve that initial implementation.
MongoMK uses a GridFS based BlobStore, separate from AbstractBlobStore in oak-mk. I could potentially come up with my own GC, based on that GridFS implementation, or I could try a new AbstractBlobStore implementation for MongoMK (not GridFS based). With the second approach, I potentially get current and future garbage collection improvements for free. Not sure which path to follow yet but I wanted to see what others thought before starting to work on it. Thanks, Mete [0] https://issues.apache.org/jira/browse/OAK-377
