It creates union of joined data streams.
It creates union of joined data streams. Produced variable will be a map which looks like: { key: result_of_evaluation_of_key_expression_for_branch1 branchId: result_of_evaluation_of_value_expression_for_branchId } branchId field of map will have Unknown type. If you want to specify it, you can pass type as a Map in definition parameter.

This is general usage state transformation.
This is general usage state transformation. It takes previous value of state and transform it using newValue lambda parameter (having previous as a parameter). Transformation is done only when transformWhen expression is satisfied. States has Time-To-Leave defined by stateTimeoutSeconds parameter. So it is generally doing something like this: newStateValue = if (transformWhen) { newValue(previous) } else { previous }
