<div style="word-wrap:break-word">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. <div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">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.<br>
