Torque: Domain definitions?
Does Torque provide (or plan to provide) support for datatype domains?
Domains are a means to define datatypes at the top of the script; what
I'd like to do is have a section in the XML that reads
<domain name="SHA" type="CHAR" length="20" />
and use it as
<column name="OBJECT_ID" type="SHA" />
Then, in Oracle or Sybase, this would resolve to something like
execute sp_addtype OBJECT_ID, 'char(20)'
whereas, in MySQL (where I don't think domains are supported) Torquen
would need to resolve and substitute these user-defined types in the
SQL generation.
This allows me to make global datatype changes with semantic scope,
for example, to change the length of all my OBJECT_ID's without also
changing all other domains which just happen to resolve to char(20).

No hurry. :)

Previous solutions to this problem involved increasing the JVM stack
and heap size (i.e. java ... -Xms128m -Xmx128m FooClass).

Yes, the memory issue was resolved. However, if you are dealing with a large
schema, you may still need to increase the default JVM stack size. If you
look at your "ant" script, you can see that setting the JAVACMD env variable
will allow you to pass parameters to the java app...
Something like this (assuming t/csh)...
setenv JAVACMD "java -mx256m -ms256m"
ant

Torque is throwing a strange exception and when I examine the generated sql
it is half finished. I am dealing with a big scheme so I am assuming it is
probably a memory issue. Did the memory issues with Torque that have been
discussed on this board before ever get resolved?
If not, how do I boost the amount of memory that ant uses to run Torque?
Any help will be much appreciated.

Deal .. All I have to do now is understand how XML works and then how
Torque works --- I hope you're not in a hurry :)

It doesn't currently support such a feature, but I would be +1 on its
addition if you submitted such a patch.
