    Description

      This ticket is meaningful in the context of sharded $lookup and distributed transactions, when these features are eventually available. The idea is to minimize the number of distributed rounds for 2 phase commit and/or minimizing the amount of data which needs to travel on the network in order to answer a $lookup.
