Recursive transforms enable "state-based" transformations within Ascend. A common pattern may be to create the 'latest' version of a Users table from a Users changelog stream. As opposed to reducing across all partitions to create the latest state, it is possible to derive the latest state from the previous state and appropriately applying the incremental data.
The video below demonstrates an overview of Recursive transformations and how to get started.
