Batch delete BigTable tables and BigQuery datasets

Question

I searched around to find a way to Batch delete BigTable tables and BigQuery datasets (using python's library) without any luck up to now.

Is anyone aware of an efficient way to do that?

I looked into these links but nothing promising:

1. BigQuery
2. BigTable

Im looking for something similar as this one coming from datastore documentation:

from google.cloud import datastore

# For help authenticating your client, visit
# https://cloud.google.com/docs/authentication/getting-started
client = datastore.Client()

keys = [client.key("Task", 1), client.key("Task", 2)]
client.delete_multi(keys)

Batch delete

I think it's not possible natively, you have to develop your own script.

For example you can configure all the tables to delete, then there are many solutions:

• Develop a Python script, loop on the tables to delete and use Python Bigquery and Bigtable clients: https://cloud.google.com/bigquery/docs/samples/bigquery-delete-dataset https://cloud.google.com/bigtable/docs/samples/bigtable-hw-delete-table

• Develop a shell script, loop on the tables to delete and use bq and cbt (from gcloud sdk): https://cloud.google.com/bigquery/docs/managing-tables?hl=en#deleting_a_table https://cloud.google.com/bigtable/docs/cbt-reference?hl=fr

• If it's possible on your side, you can also use Terraform to delete multiple Bigquery and Bigtable tables, but it's more adapted if you need to manage a state for your infrastructure: https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/bigquery_table https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/bigtable_table
