Suggestion: New table iterators
Thu Oct 19 12:54:55 CEST 2000
I'd like to add my support for iterators over ets/dets/mnesia.
At the moment writing a safe iterator over an mnesia table is not obvious if
you want to also have concurrent updates. Apart from anything else there
appears to be no guarantee that a table will not be re-hashed during the
iteration - even in a transaction.
If you want to delete stuff during the iteration it is even less obvious how
to do this safely and simply. Building a list of stuff to be deleted later
can chew up masses of memory..
