python how to get all kind names in google cloud datastore

Question

I am wondering how to retrieve all kind names that are stored in the google cloud datastore in Python. I am thinking of using a query,

client = datastore.Client()
query = client.query()
results = query.fetch()

but it only gets all the entities stored by the default client. So how to get all the kinds' names in this case?

Answer 1

You can use a kind metadata query to fetch the kind names.

If you're using the Google Cloud Python library, it would look like:

query = client.query(kind='__kind__')
query.keys_only()

kinds = [entity.key.id_or_name for entity in query.fetch()]
