pubsub | subscribe library

pubsub is a Python library. pubsub has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can download it from GitHub.

A client library for a publish-subscribe service. Current implementation supports Google Cloud PubSub. pubsub automatically handles the creation of topics and subscriptions, as well as making sure subscription names do not clash, based on the app_name provided when instantiating PubSub. Messages may be anything that is JSON-serializable (can be fed to json.dumps). pubsub will take care of encoding and decoding messages in a format compatible with the service used. WARNING: under Delivery contract, Google PubSub documentation states: For the most part Pub/Sub delivers each message once, and in the order in which it was published. However, once-only and in-order delivery are not guaranteed: it may happen that a message is delivered more than once, and out of order. Therefore, your subscriber should be idempotent when processing messages, and, if necessary, able to handle messages received out of order. If ordering is important, we recommend that the publisher of the topic to which you subscribe include some kind of sequence information in the message.
