"
The main idea of this series is to provide a filtering_visitor
as a specialised result_set_builder::visitor implementation
that keeps restriction info and applies it on query results.
Also, since allow_filtering checking is not correct now (e.g. #2025)
on select_statement level, this series tries to fix any issues
related to it.
Still in TODO:
* handling CONTAINS relation in single column restriction filtering
* handling multi-column restrictions - especially EQ, which can be
split into multiple single-column restrictions
* more tests - it's never enough; especially esoteric cases
like filtering queries which also use secondary indexes,
paging tests, etc.
Tests: unit (release)
