Hi folks, I mentioned in last week's perf call that I've been experimenting with the Seastar library [1] to see how well it can integrate with the ceph codebase. So far I've managed to add bufferlist conversions to/from the seastar buffer types, and build up a seastar messenger that can send/receive ceph Messages. The branch [2] includes a simple echo server unit test and a README with build instructions. This follows some prototype work a couple years ago by Adam Emerson and myself, dubbed Project Crimson [3], to evaluate Seastar as the basis for a low-latency OSD. Interesting parts of this project include a Cap'n Proto-based messenger and an async ObjectStore interface with Memstore implementation.
So after I saw your initial work on project crimson a month or two ago I went out and started working through the seastar tutorial. I never really got past screwing around with it since I've been tied up in other stuff, but it seems like you must like seastar enough to be willing to sink some time into it. Where are you planning on taking this next?
