Saves data into a storage under an identifier you choose, so a later step or run can read it back. Use it to keep a value or a whole record around between steps, to build up a lookup table, or to remember something across runs. If an item with the same identifier already exists, it is overwritten. The data flowing through your transformation is passed along unchanged, so saving never alters the entity you are working with.

Sample data

This transformer writes to a configured storage backend and leaves your data unchanged, so there is no fixed before and after to show. The example below stores the whole entity under the identifier taken from its sku field. With Source set to name, only that single value would be stored under the same identifier instead.
