MDL scalability regression after backup locks

    XMLWordPrintable

Details

    Description

      In 7a9dfdd GLOBAL and COMMIT namespaces were combined into BACKUP, which doubled load on BACKUP lock mutex.

      Can be fixed by implementing something similar to MySQL WL#7306 "Improve MDL performance and scalability by implementing lock-free lock acquisition for DML".
