Property Description

If the map/reduce process includes a map stage, the reduce keys are the keys written by mapContext.write(options).

If the map stage is skipped, the reduce keys are provided by the getInputData stage:

  • If the input type is an array, the key is the index of the element.

  • If the input type is an object, the key is the key in the object.

  • If the input type is a result set, the key is the internal ID of the result.

Note:

Each key cannot exceed 4000 bytes.
