" 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) " * 'allow_filtering_6' of https://github.com/psarna/scylla: tests: add allow_filtering tests to cql_query_test cql3: enable ALLOW FILTERING service: add filtering_pager cql3: optimize filtering partition keys and static rows cql3: add filtering visitor cql3: move result_set_builder functions to header cql3: amend need_filtering() cql3: add single column primary key restrictions getters cql3: expose single column primary key restrictions cql3: add needs_filtering to primary key restrictions cql3: add simpler single_column_restriction::is_satisfied_by
