Random Split Step

The Random split step selects one branch for each run according to configured probabilities. It is available in both automation types.

Configure Branches

Open the step on the workflow. A new step's Probabilities block already contains two branches with a weight of 1. Each branch has a 50% probability.

For each row, enter a branch name and set an integer weight from 1 to 100 with the slider or by typing it. A name is required and can contain up to 80 characters.

Add creates a branch with a weight of 1, and the trash button removes one. Existing branches do not need to be recalculated. A step must retain from 2 to 10 branches.

A percentage is calculated by dividing a branch's weight by the sum of all branch weights. For example, weights 1 and 1 produce 50% and 50%, while weights 1 and 3 produce 25% and 75%. You can still enter 25, 25, and 50 to get the same percentages. The weights do not need to total 100. When percentages are rounded to whole numbers, the remainder is distributed between branches so the displayed total is always 100%.

Connect Every Output

Each row creates its own output with the same name. Connect every output to a following step. An unconnected branch does not block publication, but the editor shows a warning and a run that chooses it ends at the split step.

The choice is calculated once for the combination of this run and this step. If the same run task is retried after a temporary error, it uses the same branch. Calculated percentages are shown in the editor and on the workflow. They describe distribution over many runs and do not guarantee an exact ratio in a small sample.
