Dmitry Lychagin resolved ASTERIXDB-997.
---------------------------------------
    Resolution: Fixed

There does not seem to be a immediate need for this rewriting. 
Distinct issues were addressed by 
https://issues.apache.org/jira/browse/ASTERIXDB-2078 

Currently there're logical/physical operators for distinct. Distinct physical operators use
runtime of the groupby operators ( both regular / micro )
