InnoDB: don't take trx_sys.mutex in ReadView::open()

    XMLWordPrintable

    Details

      Description

      This is something that wasn't addressed during the large trx_sys refactoring. Taking trx_sys.mutex is bad for 2 reasons:

      • it is not intended for synchronisation between purge and connection threads
      • it is a global mutex on a hot-path that can be avoided.
