- I think it is very important to implement in same way for
non-rdbms or rdbms provider whenever it is possible ( regardless of if
there is speed improvement or not)
I think in this case this new interface can be implemented for non-RDBMS
- How would application knew which FDO Schema name to set
before calling FdoIEnumerateFeatureClasses interface ?
- I am not sure how much applications would really benefit from
this. There were big speed problems with DescribeSchema but I don't
think it is problem with Describe Schema itself. I think MapGuide as
application was problem, calling DescribeSchema in too many functions.
Than providers created cache of it instead of application using it in
more optimized way. Now application can't get new schema even if
application would request for it. You need to restart server.

Subject: [fdo-internals] RFC 23 for Review
RFC 23 (http://trac.osgeo.org/fdo/wiki/FDORfc23) has been posted. This
RFC proposes APIs for retrieving feature class information without
having to perform a full DescribeSchema. The main benefit will be
improved performance in applications connecting to RDBMS datasources.
Please review the proposal and reply to this list with your comments by
July 15, 2008.
