#### **General description**

The Group records Transformer helps group entities from a list based on a value of a property of the entities in the list.

For example, if a list of products contains a property called “parent\_sku”, this Transformer can group the products into an object. The resulting object will contain keys for each unique parent\_sku. The value will be a list of entities with the parent\_sku.
