No chunk splits when using findAndModify() to upsert

    • Priority: Icon: Major - P3 Major - P3
    • 2.1.1

    • Component/s: Sharding
    • None
    • ALL

      Doing upserts on a sharded collection via a findAndModify will not initiate chunk splits (and subsequent balancing).

      I've attached a javascript file that shows the correct behavior for a regular upsert and reproduces the bug behavior for a findAndModify upsert.

      Before running, please start a sharded cluster using the mongo snippet with chunksize=1 or increase n.
