Component/s: Aggregation Framework
I'm running aggregations against 12 shards. This is with wired tiger.
The aggregation is a complex project then a group with sum.
I see first the aggregation run on 8 shards
then run on the remaining 4 shards
then a brief flurry on the primary shard.
Why is this - should all 12 not run in parallel.
