keyPrefix property
The key_prefix for this database.
This key_prefix is used, in combination with the project id ("") to
construct the application id that is returned from the Cloud Datastore
APIs in Google App Engine first generation runtimes. This value may be
empty in which case the appid to use for URL-encoded keys is the
project_id (eg: foo instead of vfoo).
Output only.
Implementation
core.String? keyPrefix;
