SubscriberAdminClient.pull vs. Subscriber for Google Cloud PubSub

Question

The Google Cloud PubSub guide on pull subscriptions uses Subscriber to consume messages from a subscription. However, SubscriptionAdminClient also has a pull method . The latter is not explored in the guides.

They both work, but is one (likely the former) recommended over the other?

Answer 1

The pull method in SubscriptionAdminClient is really only exposed because it is part of the auto-generated library. Whenever possible, it is best to use the Subscriber library, which is a hand-written library designed to optimize for high throughput and low latency. The pull method is covered in the documentation , though accessed in a slight different way.
