Implement parallel CREATE INDEX, ALTER TABLE, or bulk load

    XMLWordPrintable

Details

    Description

      ALTER TABLE in InnoDB is single-threaded, except for the special case ADD FULLTEXT INDEX, which creates additional threads to create the partitioned inverted index in shorter time.

      We should refactor ADD FULLTEXT INDEX to make use of the MDEV-16264 work queue and make ADD INDEX use of the background threads as well. To avoid disparity with smaller items in the work queue, the work should be split into smaller items, such as "merge sort 2 blocks" or "copy a sorted block to index pages".
