    XMLWordPrintableJSON

Details

    • Major Change

    Description

      Change index key format to no longer use BSON in WiredTiger.
      Benefits include:

      • much faster key comparison
      • reduced storage size for indexes
      • take much better advantage of WT key prefix compression
      • no longer require custom collator, which means stock WT tools like repair work with no modification

      As this is an on-disk format change, indexes created before this change with WT will no longer be usable without running:
      mongod --storageEngine wiredTiger --repair
