Review request for drill, Aditya Kishore, Aman Sinha, Jacques Nadeau, Jinfeng
Ni, Mehant Baid, and Parth Chandra.
Changes
-------
Fix failing testcase with small change to the cost calcuation of an
EasyGroupScan in the case of very small files. Also fixed matierializing null
outputs from folded constant expressions.
Bugs: DRILL-2060
https://issues.apache.org/jira/browse/DRILL-2060
Repository: drill-git
Description
-------
THIS REQUEST HAS BEEN BROKEN INTO TWO REVIEWS:
- I had to make a fairly substandial change to the interpreteed expression
evaluation to make the tests work.
Use a small modification of a rule in optiq and hook up the interpreted
expression evaluator to fold constant expressions (including those with Drill
UDFs) into literals. Fragment memory limits have been disabled, a more complete
refactoring of memory management is planned, the changes made here were to
allow the creation of a childAllocator without access to a fragment context. I
have added two comments next to the modifiations I made to the optiq rule for
our use case.
