 Description   

We should confirm that the following events do not lead to correctness problems when they happen concurrently with an $out stage:

  • The primary shard is moved.
  • A shard contributing to the aggregation is removed.
  • A new shard is added.

It is acceptible for the $out to fail in any scenario, but it should not write orphaned data or anything else like that.
