(http://hackage.haskell.org/package/KyotoCabinet)http://hackage.haskell.org/package/KyotoCabinet As far as I know, persistent doesn't depend on any particular backend, but as far as NoSQL-stuff goes, I think there's only persistent-mongodb at the moment. I don't know how much work it is to create a new backend (and if it's worth the effort in your case), but this looks like a good place to start: http://hackage.haskell.org/packages/archive/persistent/0.6.4/doc/html/Database-Persist.html#t:PersistBackend Cheers, Daniel pgpJFU0H52TZ9.pgp Description: PGP signature ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] Easiest to use NoSQL storage with Haskell?
Hi, What Haskell package to work with NoSQL storage is both mature and easiest to use? I need persistent storage for simple key/value lists (not complex JSON docs). CouchDB and Cassandra seems to be overkill for my needs. What about Riak, MongoDB, Voldemort, etc. ? Thanks!

If your data fits in RAM then acid-state is also an option: http://hackage.haskell.org/package/acid-state It's used as the storage library for the new hackage server.

Re: [Haskell-cafe] Easiest to use NoSQL storage with Haskell?
TCache manages persistent data trough STM references called DBRefs that are very similar to TVars, but with added user-configurable persistence. Very intuitive to use. 2011/11/9 Bas van Dijk v.dijk@gmail.com: On 9 November 2011 19:50, dokondr doko...@gmail.com wrote: On Wed, Nov 9, 2011 at 8:41 PM, Bas van Dijk v.dijk@gmail.com wrote: On 9 November 2011 11:59, dokondr doko...@gmail.com wrote: What Haskell package to work with NoSQL storage is both mature and easiest to use?
