Spanner Client

Instantiating a Client

To use the API, the Client class defines a high-level interface which handles authorization and creating other objects:

from google.cloud import spanner client = spanner.Client()

For an overview of authentication in google.cloud-python, see Authentication.
In addition to any authentication configuration, you can also set the GCLOUD_PROJECT environment variable for the Google Cloud Console project you’d like to interact with. If your code is running in Google App Engine or Google Compute Engine the project will be detected automatically. (Setting this environment variable is not required, you may instead pass the project explicitly when constructing a Client).
After configuring your environment, create a Client

>>> from google.cloud import spanner >>> client = spanner.Client()

or pass in credentials and project explicitly

>>> from google.cloud import spanner >>> client = spanner.Client(project='my-project', credentials=creds)

After a Client, the next highest-level object is an Instance. You’ll need one before you can interact with databases.
