Connecting to Quix Cloud

Why Use Quix Cloud

Quix Streams was made to seamlessly integrate with the Quix Cloud.

When running Quix Streams on Quix Cloud, all connection and authentication-based settings are preconfigured for you.

Quix Cloud itself provides a frictionless environment to deploy and manage your applications using either our API or our browser-based UI.

To learn more about Quix Cloud and how to set up a project, please see the Quix Cloud docs.

Can I Use Quix Streams With My Own Kafka?

Using Quix Streams with Quix Cloud is entirely optional.

You could, for example, connect to Redpanda Cloud, or another supported broker, or connect to a self-hosted broker.

Connecting with Quix Streams

Here is how to connect to the Quix Cloud Kafka brokers using Quix Streams:

Within Quix Cloud

If you are running your Quix Streams Application directly within Quix Cloud, it's configured automatically.

Just make sure broker_address is NOT set:

from quixstreams import Application

app = Application()

OR

from quixstreams import Application

app = Application(broker_address=None)

Outside of Quix Cloud

1. Obtain SDK Token

First, get your SDK Token.

NOTE: A Personal Access Token (PAT) is also accepted, but often requires more configuration due to raised privileges. We recommend using the SDK Token.

2. Pass SDK Token to Application

With your SDK Token and a Quix Streams Application, you can pass it using one of these approaches:

Set Environment Variable (recommended):
- Simply set Quix__Sdk__Token (double underscores!) to your SDK Token
  
  NOTE: Quix__Sdk__Token is set automatically in Quix Cloud, thus is the recommended approach for an easy migration.

OR

Application argument
- Just do:
```
from quixstreams import Application

app = Application(quix_sdk_token="MY_TOKEN")
```
  WARNING: This value is prioritized over Quix__Sdk__Token, which may cause ambiguity if both are set.

3. Validate it Worked!

When you initialize your Application(), a message should be logged letting you know it will connect to Quix Cloud when Application.run() is called.

If not, you'll need to double check your settings and try again!

Local Development to Quix Cloud

For those wanting to develop with a local broker and then migrate to Quix Cloud, here is a recommended example pattern that avoids code changes:

from quixstreams import Application
import os

app = Application(broker_address=os.getenv("YOUR_ENV_VAR", None))

Just pick an environment variable and set it to your local broker address!

In Quix Cloud it will default to None as desired and use the Quix Cloud environment.
