Docs for SERVER-33998: Remove the parallelCollectionScan command

    • Type: Icon: Task Task
    • Resolution: Fixed
    • Priority: Icon: Major - P3 Major - P3
    • 4.1.1
    • Affects Version/s: None
    • Component/s: None
    • Labels:


      Original Description


      The parallelCollectionScan command is no longer supported.

      Engineering Ticket Description:

      In its current form, the parallelCollectionScan command will only return multiple cursors when running a mongod with the MMAPv1 storage engine. With the deprecation of MMAPv1 we should also deprecate parallelCollectionScan.

      If the ability to partition a collection is required under WiredTiger in the future, it is likely it will take a different form than parallelCollectionScan. Once such request is tracked by SERVER-24274



      Scope of changes (files that need work and how much)

      • Remove the command page and associated files
      • 4.2
      • 4.2-compatibility
      • add redirects

      Impact to other docs outside of this product

      Atlas lists the command as one not supported (so, need to create ticket for atlas but due for much later – next year)

      MVP (work and date?)
