Unused or useless InnoDB counters num_index_pages_written, num_non_index_pages_written

    XMLWordPrintable

Details

    Description

      The InnoDB counters num_index_pages_written and num_non_index_pages_written were added in MariaDB Server 10.1.0 and inadvertently disabled in MariaDB Server 10.2.2 when the instructions to increment these counters were removed from the function fil_io().

      Let us remove these counters that never reported anything useful. If such statistics are really needed in a special case, they can be obtained by instrumenting the code by some means, such as eBPF or a source code patch.
