------------------------------------
Hi Dmitriy,
I verified with PigStorage and AvroStorage that there is no regression.
Nevertheless, it is probably a good idea to run a full test suite for this kind
of change, so I've kicked off unit test and e2e test. I'll let you know if they
all pass.
Thanks!

> Currently the regex match operation does not get pushed down to LoadMetadata
> (and Expression does not have an enum value for it); it would be quite useful
> to enable this for some optimizations.
