(11:37:44 AM) mattbenjamin: sjusthm, cbodley: Casey and I think it might be useful to have a short video call on the meet points between object and collection handle as we did it, and the other objectstore changes; I don't know which aspects really should port over to master, but I think it would be useful to do a walk-through and discussion of what parts we could retarget, and anything that we could sequence cleanly later. (11:38:06 AM) mattbenjamin: sjusthm, cbodley: do you have a bit of time available?
Some of the pieces we had: 1. the handle interface change itself 2. indexed slots for collection and object handles or ids (unions, iirc) in Transaction, and efficient operations to fill slots 3. probably more flexbility than needed in that every OS could completely redefine Collection and Object 4. lifecycle and refcounting which worked correctly 5. an Object hierarchy we actually used in our version of filestore, w/concurrent LRU system 6. a set of changes by Casey replacing the FDRef system w/management of objects--some of this could be useful, I don't know how it maps onto newstore at all 7. a unification of ObjectContext and opaque Object which we were debating in Oregon 8. thread-local caches of collections and objects above the OS interface that appeared to be a big help in IOPs work ok, apparently we're on for 11:00 am pst--I'll send an invite Matt -- Matt Benjamin Red Hat, Inc. 315 West Huron Street, Suite 140A Ann Arbor, Michigan 48103 http://www.redhat.com/en/technologies/storage tel. 734-761-4689 fax. 734-769-8938 cel. 734-216-5309 -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
