    Description

      This ticket tracks the knob that may be added to control usage of the no-prefetch TaskExecutorCursor added in SERVER-73959.

      Things to consider:

      • What are the values of the knob (does a boolean suffice)?
        • What is the default?
      • How will this knob interact with the current plan of calling the no prefetch TaskExecutorCursor when there is an extractable limit in the query? Presumably the knob will trump what this optimization wants to do.
      • Will it be user-facing?
