Drop Firestore in Datastore mode

[Thin Rhino]

Hello,

We recently moved our project across regions. We moved the entire backend from the US to India DC.

We want to delete the entire "Firestore" in the US region, in the most cost effective way.

We have over 22 Billion entities across multiple tables.

We could run a dataflow job, but we will be charged for read and delete of every record + cost of dataflow.

Google Support told us to set up TTL policies on the records.

I wanted to check with folks here, if there was any other method that we can work with.

Regards
ThinRhino
