Description
During the design we agreed to the following change in merging policy:
We will change the pipeline splitting logic such that $out is not forced to execute in the merger part of the pipeline, and does not cause the pipeline to split. If $out is preceded by stages that can all execute in the shards part, then each shard will be responsible for dispatching writes to the correct shard.
