This blog post provides a solution to delete multiple entries from a FaunaDB database that match a given regex pattern. The author shares their experience with the lack of clear documentation and offers a script that can be used for this purpose. The script requires the user's secret, table name, and regex pattern as input. It initializes faunadb, retrieves matching documents using pagination, and then iterates through the results to delete matching entries. The author recommends printing the results before deleting anything to ensure accuracy.
