Details

    Description

      While the testcase does not immediately look significant (we're deleting from mysql.innodb_table_stats) note that this is likely just an artifact, i.e. the issue can likely be reproduced in other ways without deleting from innodb_table_stats. There are number of bugs open that look somewhat related (linked), but they are on older versions (except MDEV-33022 which is in combination with Galera), and this issue could be reproduced on 10.6+ only.

      # Requires standard master/slave setup
      		 
      CREATE TABLE t (c VARCHAR(2000) BINARY CHARACTER SET 'utf8') ENGINE=InnoDB;
      		 
      ALTER TABLE t ADD UNIQUE (c);
      		 
      SELECT c FROM t;
      		 
      DELETE FROM mysql.innodb_table_stats;

      Leads to (on slave):

      11.4.0 8bf9f21855606ddeb0fe90fb1e70165adbec6746 (Debug, Slave)
