New Features and Enhancements

• Improved deployed model refresh performance for models with a concept whose identity comes from columns in more than one table. Before this release, if that concept had several properties, PyRel re-read and re-joined those tables once for every property on each refresh, which was slow over large tables. Now PyRel reads and joins them once and fills in all the concept’s properties from a single pass, so each refresh does less repeated work and returns the same results.

• Improved status reporting for the REFRESH_STATUS procedure.
