This article explains how you can write the entity data into a storage.
Create a storage: go Storages -> Storages -> click "+" for new storage -> fill in the Name*, and Path of the storage* -> save & continue.
Note: the best practice is to copy the “Identifier” and paste it into the “Path of the storage*” field to make it unique because you don’t want 2 storages in the same location because it is going to override each other and result in a weird behaviour.
Then apply this storage to the transformer “Example -Get Posts for User”.
Settings: Data, transform data using mappers and conditions
Filters: Filter by stored identities (to make sure the order is not processed by the same identity twice)
Storage*: select the storage you have just created - “Consumed users”
Identifier patterns*: email
Then press “test” to see the result and go to the Storage -> Entities , this entity (email) will be stored in the storage.
