    Description

      Description

      Description:

      This commits disallow multi-statement transactions on shard servers that have writeConcernMajorityJournalDefault = false.

      Engineering Ticket Description:

      Nodes running with the in-memory storage engine do not support transaction prepare and because of this, currently they cannot participate in cross-shard transactions.

      On the chance that we start supporting that and in order to ensure that in-memory nodes and nodes running with writeConcernMajorityJournalDefault = false don't count towards the majority quorum for any w:majority writes done by the coordinator and participant, such writes should be done with j:true.

      Scope of changes

      • txn
      • txn prod concern
      • txn sharded clusters prod concern
      • rs conf page
      • For now, will not put in the limits/restriction page for sharded clusters operation.
