[erlang-questions] [ANN] Mnesia eleveldb backend 1.0

Finally, as promised: all you need in order to use Mnesia to manage
unhealthy amounts of data:

    https://github.com/klarna/mnesia_eleveldb

Apache 2.0 license. Requires Erlang/OTP 19 or later, or an earlier version
with the mnesia_ext patch added (see
http://erlang.org/pipermail/erlang-questions/2015-July/085046.html).

Most of the actual work has been done by Ulf Wiger and Mikael Pettersson.
eleveldb itself is the work of Basho; we take no credit for that.

Documentation is rudimentary; OTP 19 doesn't seem to include the actual
docs for the mnesia_ext patch yet. On the other hand, you don't need to
know much about how the plugin interface works in order to use this backend
- you simply get a new table type. See the REAME for some caveats.

You may also want to use this add-on to make backups easier:
https://github.com/klarna/leveldb_manager (we're not sure if it's needed
with the more recent versions of leveldb).
