" This series adds some optimisations to the paging logic, that attempt to close the performance gap between paged and not paged queries. The former are more complex so always are going to be slower, but the performance loss was unacceptably large. Fixes #3619. Performance with paging: ./perf_paging_before ./perf_paging_after diff read 271246.13 312815.49 15.3% Without paging: ./perf_nopaging_before ./perf_nopaging_after diff read 343732.17 342575.77 -0.3% Tests: unit(release), dtests(paging_test.py, paging_additional_test.py) " * tag 'optimise-paging/v1' of https://github.com/pdziepak/scylla: cql3: select statement: don't copy metadata if not needed cql3: query_options: make simple getter inlineable cql3: metadata: avoid copying column information query_pager: avoid visiting result_view if not needed query::result_view: add get_last_partition_and_clustering_key() query::result_reader: fix const correctness tests/uuid: add more tests including make_randm_uuid() utils: uuid: don't use std::random_device()
