    • Fully Compatible
    • Sharding 2018-12-31, Sharding 2019-01-14, Sharding 2019-01-28

      Otherwise, in a split brained coordinator shard, the old coordinator primary might receive recoverCommit and find its local participant in prepare, because the new coordinator primary received coordinateCommit, had a stale ReplicaSetMonitor for itself, and sent prepareTransaction over the network to the old coordinator primary.
