yes. but there can be a way to process dataset row by row in the
client, for example (it depends of task, of course). so you'll have 1M
in SQL helper and couple of KB in client...

or something like this. just process data chunk by chunk and don't keep
the whole data in memory.

and you always can write the time-consuming parts in the `real'
language, where Lua `hooks' calls here and there...
