[erlang-questions] large objects in dets
Thu May 10 10:05:38 CEST 2007
First a question: Is 2GB limit per file preserved even in 64-bit
Than my 2c worth:
> - should I hack dets?
IMHO: NO. It's not worth while exercise. I suspect that DETS would be very
slow in reading/writing BIG things. Secondly, you would not be able to do it
in "chunks", but a whole thing at the time.
> - should I "roll-my-own"
YES. It would make far more sense to place your big things into a normal
file (i.e. one thing per file) and use DETS table as a catalog/index of
things. But then, next question would be why DETS and not mnesia with
disk-only (DETS) or disk table (ETS + DISK LOG). That way, you'll get far
better control over your life.
