| Description |
|
$accumulator should be available only when FCV is kFullyUpgradedTo44. We need to extend the REGISTER_ACCUMULATOR macro, similar to REGISTER_EXPRESSION_WITH_MIN_VERSION. We can also mark $_internalJsReduce and $_internalJsEmit as 4.4 only. These internal operators are part of the new mapReduce implementation, and mongos should only produce them on FCV 4.4. |
