[Zope-dev] catalog performance: query plan

[Alan Runyan]

I agree with Tres.  A lot more can be done with Indexes and Catalog
without caching.

The most exiciting development in Catalog optimizations comes out
Jarn.  Helge Tesdal (iirc) did a buncha work  at a RDBMS company when
he was in college.  He has a protoype of a query plan for ZCatalog.

I would like to ask Roche and others to look at the Query Plan.

Caching is a total PITA because invalidation machinery becomes
overwhelming complex and unwieldly quickly in production.
