Chapter 10. Translator Capabilities

The ExecutionFactory class defines all the methods that describe the capabilities of a Translator. These are used by the Connector Manager to determine what kinds of commands the translator is capable of executing. A base ExecutionFactory class implements all the basic capabilities methods, which says your translator does not support any capabilities. Your extended ExecutionFactory class must override the necessary methods to specify which capabilities your translator supports. You should consult the debug log of query planning (set showplan debug) to see if desired pushdown requires additional capabilities.
