Has anyone looked at writing a cache store that uses MapDB? It provides Maps, Sets and Queues backed by disk storage or off-heap memory, with MVCC and (non-JTA) transactions. The author previously wrote JDBM (multiple versions), and has recently ventured out on his own to focus on MapDB full-time. It's only at 0.9.5, but progressing quite nicely. I've been looking at it for other uses, and quite enjoy it. http://mapdb.org _______________________________________________ infinispan-dev mailing list infinispan-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev

Looks good. Perhaps I'm missing something, but I don't see a way to persist to local disk with your cache store. Is that right? I see the advantage of having an off heap memory-based cache store, but your code is actually not too far away from a cache store that persists to a (memory-mapped) file. I'd love to see how that compares to a cache store based upon LevelDB.

MapDB is a progression on JDBM, right? https://github.com/infinispan/infinispan-cachestore-jdbm On 3 Sep 2013, at 16:55, Ray Tsang <saturnism(a)gmail.com&gt; wrote: > Good timing - I just started an off-heap store for fun that uses mapdb direct memory db. > https://github.com/saturnism/infinispan-cachestore-offheap > > Please take a look! > > > On Tue, Sep 3, 2013 at 6:13 AM, Randall Hauch <rhauch(a)redhat.com&gt; wrote: > Has anyone looked at writing a cache store that uses MapDB?

I readapted the offheap store to mapdb store. https://github.com/saturnism/infinispan-cachestore-mapdb check it out!

Ray's is actually pretty close, except that it assume that MapDB should use only the direct memory option (there are quite a few others). A combination of both would probably work really well.
