As of January 1, 2020 this library no longer supports Python 2 on the latest released version. Library versions released prior to that date will continue to be available. For more information please visit Python 2 support on Google Cloud.

The google-cloud-core package contains helpers common to all google-cloud-* packages. In an attempt to reach a stable API, much of the functionality has been split out into this package, google-api-core.

Note

Because this client uses grpc library, it is safe to share instances across threads. In multiprocessing scenarios, the best practice is to create client instances after the invocation of os.fork() by multiprocessing.pool.Pool or multiprocessing.Process.
