 Description   

----------------------------

Original Description

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

----------------------------

Description

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?)
