Description copied from interface: CommandPlanner

Allows the planner a chance to optimize the canonical plan(s) stored in the CommandTreeNode tree. This method should be called in a bottom-up manner; from leaf nodes up to the root node.

Specified by:

optimize in interface CommandPlanner

Parameters:

command - TODO

metadata - source of metadata

capFinder - Class usable to find the connector capabilities for a particular model

Returns:

ProcessorPlan implementation specific to the CommandPlanner

Throws:

QueryPlannerException - indicating a problem in planning

QueryMetadataException - indicating an exception in accessing the metadata

TeiidComponentException - indicating an unexpected exception
