[Commits] 6b21981: MDEV-7487 Semi-join optimization for single-table update/delete statements

revision-id: 6b21981eb1f61241cb4125a25e4e479164e213c0 (mariadb-10.6.1-472-g6b21981) parent(s): 596cde07f17c490c43db10ce0a8cbb7bd4dbf5ae author: Igor Babaev committer: Igor Babaev timestamp: 2022-06-18 21:44:00 -0700 message: MDEV-7487 Semi-join optimization for single-table update/delete statements This patch allows to use semi-join optimization at the top level of single-table update and delete statements. The problem of supporting such optimization became easy to resolve after processing a single-table update/delete statement started using JOIN structure. This allowed to use JOIN::prepare() not only for multi-table updates/deletes but for single-table ones as well. This was done in the patch for mdev-28883: Re-design the upper level of handling UPDATE and DELETE statements. Note that JOIN::prepare() detects all subqueries that can be considered as candidates for semi-join optimization. The code added by this patch looks for such candidates at the top level and if such candidates are found in the processed single-table update/delete the statement is handled in the same way as a multi-table update/delete.
