Hi, sage I will add rocksdb submodule into the makefile , currently we want to have fully performance tests on key-value db backend , both leveldb and rocksdb. Then optimize on rocksdb performance.
I'm definitely interested in any performance tests you do here. Last winter I started doing some fairly high level tests on raw leveldb/hyperleveldb/raikleveldb. I'm very interested in what you see with rocksdb as a backend.

There is also a commit that adds rocksdb as a git submodule. I'm thinking that, since there aren't any distro packages for rocksdb at this point, this is going to be the easiest way to make this usable for people. If you can wire the submodule into the makefile, we can merge this in so that rocksdb support is in the ceph.com packages on ceph.com. I suspect that the distros will prefer to turns this off in favor of separate shared libs, but they can do this at their option if/when they include rocksdb in the distro. I think the key is just to have both --with-librockdb and --with-librocksdb-static (or similar) options so that you can either use the static or dynamically linked one. Has your group done further testing with rocksdb? Anything interesting to share?
