[erlang-questions] [ANN] LETS - LevelDB-based Erlang Term Storage v0.5.1

[Joseph Wayne Norton]

Tristan -

Hi.  I have no plans at this moment to add match support.

There is a list of roadmap items on the overview.edoc (https://github.com/norton/lets/blob/master/doc/overview.edoc#L250) file.

thanks,

As in, would it be more like using an external DB than Mnesia. This actually is something I would like since I want to use an Erlang term storage but I want to be able to use services like Dotcloud that separate out database and web services.

DETS is limited by a 2 GB file size limitation and does not implement ordered sets. LETS has neither of these limitations.
