Tom,

Thanks for the new release.

Our Grouper group registry is not yet live, but will be soon.
It will replace the production system sometime this summer.
I'd like to upgrade to 1.6 before that rather than afterward.

The new "flattened memberships" table concerns me for a couple
of reasons.  First, it requires the change log be enabled, which we
don't do.  Second, it appears to contain a record for each effective
member of each group.  Correct me if I'm wrong there.

We already have over two million records in the 'direct membership'
table, grouper_memberships.  We have many large groups (over 100K
members) that are themselves members of many other groups.  I can
see the flattened memberships table easily reaching 10 to 20 million
records -- and to what point?  Most of the activity of the registry
deals with direct membership, not effective membership.

So my question is: What is the consequence of running without the
change log, ignoring the flattened memberships table altogether?
Are there any core functions of grouper that are going to depend
on this table?

Thanks,

Jim
