14:00 <apostolis> I am looking for a good database for mirage. (a key value store) . Has anyone tried lmdb? Any other KV stores?

14:01 <apostolis> https://github.com/Drup/ocaml-lmdb

14:15 <hannes> apostolis: i have not, but i have been using the mirage-kv _interface_ (https://github.com/mirage/mirage-kv) quite a bit -- there are implementations for unix filesystem (mirage-kv-unix), in-memory (mirage-kv-mem), and git remote (irmin/git). if the interface is appealing, it would be nice to have e.g. sqlite3 and lmdb backend for it

14:22 <apostolis> hannes : it seems that lmdb uses pthread.h , so I doubt it can be used in mirage.

14:22 <apostolis> Which of the three is the fastest and is persistent?

14:22 <hannes> true, well, not in the mirage-as-a-virtual-machine, but e.g. in mirage-on-unix

14:23 <hannes> kv-mem is not persisten, kv-unix is only available on unix, git is supported via git protocol (tcp) or http(s) [i've some branches which enable git+ssh as well]

14:24 <hannes> but if you need a high-performance database, i guess you'd want to have no network overhead -- i.e. current options seem to be available only on unix anyways (though with a block device it may work)

14:32 <apostolis> I don't know what to do. I was hoping to use a db for both mirage and linux. Maybe I should stick to linux for the moment.

14:42 <hannes> to me it sounds sensible to first stick to linux, and figure out what the application uses/needs.

14:43 <apostolis> I want to capture all IO input into a database.

14:45 <apostolis> It sounds sensible to stick to linux, then.

23:07 <cbarrett> I'm curious about improving mDNS support in ocaml-dns. Is that an area where a new contributor could get started?
