Storage-engine private data area per physical table

Details

    • Task

    Description

      We need a data area per physical table where storage engine can store anything it wants.
      Additionally, this should store engine_options, tablefile path, etc. It cannot be directly in the TABLE_SHARE, because partitions have different paths and engine_options.

      We cannot directly backport MySQL WL#4305 (see the link below), because it was reverted by Oracle and, anyway, it doesn't solve the problem of different paths and engine_options.

            Attached the work-in-progress patch for 10.0-base tree.

            Left to do:

            • don't pass table name into handler::open()
            • use handler_share in almost all engines
            • move connect_string and other engine options into engine_options.
            • support per-partition engine_options

            I have removed the fixVersion for this task as it is one of 5.5, 10.1, 10.2, 10.3, which are EOLed.

            Please add a new fixVersion if you plan to work on this task for a not EOLed versions.
