    Description

      WiredTiger recently completed an investigation of the feasibility of removing enableMajorityReadConcern:false now that WT has durable history. After reviewing the findings of that investigation, we are moving forward with Removing Support for enableMajorityReadConcern:false. Durable History addresses cache pressure concerns around majority commit point lag allowing for the removal of eMRC:false (a mode of operation that does not allow distributed transactions and other features).

      We need to disable support for eMRC:false as a first step.

      In a future release, we will fully remove support for eMRC:false.
