    Description

      From DOCS-7979

      I reported some inaccurate information via DOCS-5682, saying that size and count is updated every 1000 document writes. As clarified in SERVER-24266, we update the in-memory cache every 1000 document writes, but the updates only become persistent when WiredTigerKVEngine::syncSizeInfo is called, most commonly every 60 seconds as part of WiredTigerKVEngine::haveDropsQueued.

      This means that number can drift much more in the event of an unclean shutdown (as much as 60 seconds worth of writes).

      Apply this correction to:
