The output location for row and cogroup functions is determined by the function:

  • If the function is vworker specific, the output goes to that vworker.
  • If the function is partitioned, the output is partitioned in the same way.
  • If the function is replicated, the output is replicated.

If the input is located on the queen:

  • If the inputs are row or dimension inputs, the output is replicated to the vworkers.
  • If the input is partitioned, the output is also partitioned.
