Review request for drill and Jacques Nadeau.
Bugs: DRILL-2406
https://issues.apache.org/jira/browse/DRILL-2406
Repository: drill-git
Description
-------
To enable planning rules to take advantage of constant expressions in queries,
or to allow them to run queries against small datasets, such as partition
information we need to e able to evaluate expressions at planning time.
Expression evaluation in the regular expecuation path is relatively expensive,
as it invovles java code generation, compilation and JITing expression trees.
An interpreted expression system was added recently to allow evaluating an
expression without generating java code at runtime. This patch exposes that
work (after some refactorings in 2143 and the first part of 2406) to the
planning context for use in optimizer rules.
