Worked example

Inputs

Shuffled dataset
1000 GB
Workers
20 workers
Transferred to raw ratio
40 %

Expected results

Remote transferred bytes
380 GB
Mean outbound per worker
19 GB

How to use this tool

  1. Enter shuffled dataset, workers, transferred to raw ratio in the displayed units.
  2. Calculate the scenario, then compare it with measurements before changing a system.

Try this example

{
  "size": 1000,
  "workers": 20,
  "compressed": 40
}

Accuracy and scope

Uniform destination distribution and one local partition per worker; retransmits and serialization overhead excluded.
