revision-id: 894c902c67ca1316a3548472731a0fe6f9795d6f (mariadb-10.10.1-19-g894c902) parent(s): a5824d8f6940dbb04b56f6641a44fd3aa843d88b author: Igor Babaev committer: Igor Babaev timestamp: 2022-09-16 22:30:50 -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.

[Commits] 0310347: MDEV-7487 Semi-join optimization for single-table update/delete statements
by IgorBabaev 16 Sep '22

16 Sep '22

revision-id: 031034711a08dbc5cf092b7017e2d0a9124d3607 (mariadb-10.10.1-16-g0310347) parent(s): 845af351eea0e0d5cb1b61e1d4fbccec5eb610e0 author: Igor Babaev committer: Igor Babaev timestamp: 2022-09-16 14:59:56 -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.

[Commits] be1024e: MDEV-7487 Semi-join optimization for single-table update/delete statements

revision-id: be1024ee16a9636679b3a1947514e2821747a673 (mariadb-10.10.1-16-gbe1024e) parent(s): 845af351eea0e0d5cb1b61e1d4fbccec5eb610e0 author: Igor Babaev committer: Igor Babaev timestamp: 2022-09-16 10:43:51 -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.

[Commits] f78fcd3: MDEV-29350 Crash when IN predicand is used in eliminated GROUP BY clause

If this clause used a IN/ALL/ANY predicand whose left operand was a single-value subquery then execution of the query caused a crash of the server after invokation of remove_redundant_subquery_clauses(). The crash was caused by an attempt to exclude the unit for the single-value subquery from the query tree for the second time by the function Item_subselect::eliminate_subselect_processor(). This bug had been masked by the bug MDEV-28617 until a fix for the latter that properly excluded units was pushed into 10.3.
