 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.
