    XMLWordPrintable

Details

    Description

      This tasks relates to analysing performance of the implementation of packed sort keys in MDEV-21580.

      First part of testing this would be

      • use the random-generated latin1 varchar dataset introduced in MDEV-21263 (with more rows)
      • take integers and/or dates and make sure we didn't introduce a regression [can use dbt3 queries for this]
