Interesting idea. You *might*, however, be able to do what
you're looking for with a regular expression (specified with
-i). I'm no regex guru, but it should be possible.

A fair number of tables, say 60% or so are 'achival' without
FKeys and the like. Still it is pretty nice to be able to
get a schema map on this.

I was thinking the other day that it would be nice to have a
flexible filtering mechanism, perhaps in the form of a java
class that could be picked up via a plugin mechanism.

It's amazing that it actually worked with over 5000 tables!

Hi - I ran a test yesterday against the schema that was
failing previously (which has been 'augmented' over time to
currently 5018 tables). Under the same conditions
(Xmx=1584m) version 3.1 successfully completed. I am also
under the impression that there was a speed enhancement,
however I don't have an actual record of run times under
controlled conditions to prove it.

Thanks!

This should be fixed in 3.1.0. Let me know if it isn't.

If this bug was opened by Amihay
(http://sourceforge.net/forum/forum.php?thread_id=1457002&forum_id=462850)
then it's probably already been resolved.

I assume that you've tried bumping up -Xmx. Does it seem to
progress further when you do that? Can you tell how far it got?

The amount of memory required should map to the size and
complexity of the schema. I can't really check for
traditional memory leaks because the object hierarchy, by
design, grows as it gathers more information.
