> The expression interpreter currently available in Drill cannot be used at planning time,
as it does not have a means to connect to the direct memory allocator stored at the DrillbitContext
level. To implement new rules based on evaluating expressions on constants, or small datasets,
such as partition information this limitation must be addressed.
