title: Batch process in firebase to delete data stored for a month
body: <p>I'm working with an AngularFire application and the data I store in fireBase has a creation date. I want to erased all the data that has been stored from a month up to today's date. Example if "x" object was store on April 9th and Today is May 9th, it should be deleted automatically, so according to the documentation you can have <a href="https://firebase.google.com/docs/firestore/manage-data/transactions" rel="nofollow noreferrer">Transactions and Batched Writes</a>. Is it possible to accomplish what I want? or I will have to write a code on the Angular side and every time someone opens the app will check the date and erase what has been stored for a month. I know for Oracle databases this can be accomplished with a batch script, so I was thinking if for FireBase could be done too.</p>
