Hi Vlad,

My understanding is that dets lookups do involve disk-lookup latencies. But maybe ETSHandler will provide the functionality you need.

I was thinking of an ets+dets combo, but it may be tricky to get the details right. Is there something like this out there? Would it be better to just use mnesia? I'd like to keep it lean, but if third-party databases fit the bill, I will look at them.
