[Maria-developers] MDEV-27776 EXPLAIN is about to get new columns, EXPLAIN EXTENDED|PARTITIONS will be deprecated

* EXPLAIN SELECT prints "partitions", "filtered" columns and produces the warning with rewritten query * EXPLAIN EXTENDED and EXPLAIN PARTITIONS produce the same output as EXPLAIN SELECT and two warnings, the second warning is about EXPLAIN EXTENDED| PARTITIONS being deprecated (same as in MySQL 5.7) -- Best regards, ------------------------- *Oleg Smirnov* Sr. Software Engineer MariaDB Server Team
