​
Delete a collection

Permanently delete a collection and all of its associated data and resources. This operation cannot be undone. 
from lambdadb import LambdaDB

lambda_db = LambdaDB(
    server_url="PROJECT_URL",
    project_api_key="YOUR_API_KEY"
)

lambda_db.collections.delete(collection_name="collection-to-delete")
Deleting a collection is irreversible and will permanently remove all documents and metadata. Make sure you have proper backups if needed before proceeding with this operation.
