Maybe acid-state [1]? [1] http://hackage.haskell.org/package/acid-state-0.12.1/docs/Data-Acid.html On Wed, Dec 18, 2013 at 7:58 PM, Andrew Cowie < andrew@operationaldynamics.com> wrote:
I have a Map. It's a lovely Map, with keys and values and everything. It's not _that_ large. Few 10s of MB at most. Unfortunately, I need to persist it somewhat reliably.
I'd somewhat like to avoid having to use an external database (obviously a key/value store like Riak would work, but that's a major dependency to impose on the system) so I'm wondering if there is a low tech way to do this.
I can control concurrent access to the file (or whatever), and the file system is robust. So that part is fine. I just need to externalize the map.
I'm wondering if just using cereal or so would be sufficient (there is a Serialize instance, of course), or whether I should be using some acid-state thing, or a Haskell binding to gdbm, or sqlite, or...
Any suggestions?
