      Hi!

      It would be nice if I can tell WiredTiger that secondary key for an index is "immutable", i.e. it won't be modified during lifetime of the record.
      We use this feature extensively with BDB (see DB_IMMUTABLE_KEY flag in DB->associate()).
      For custom index key extractors this can provide performance improvement.
