    Use the Playground to practice and learn more about SQL++.

    The Playground lets you try out SQL++ code examples through interactive tutorials inside the Couchbase Capella UI.

    How the Playground Works

    The code examples in the Playground run in a remote execution environment deployed in the USA, which imposes limits to the runtime of each programming language. The remote environment has a firewall that prevents access to domains or networks outside of the Couchbase Cloud environment.

    When you run a code example on the Playground, Couchbase Capella:

    • Generates a temporary credential for you with read and write access to the bucket you used for the code example. This temporary credential is destroyed after your code example request is executed.

    • Provides the remote execution environment with temporary network access to your cluster. This temporary network access is automatically revoked after 1 hour.

    For security purposes, do not include your cluster access credentials in your code examples.

    Prerequisites

    Before you use the Playground, make sure that you have access to the travel-sample bucket on your cluster.

    If you do not have access to the travel-sample bucket, import the sample data or open a support ticket.

    Use the Playground

    To use the Playground:

    1. Go to Playground and select 1 of the following tutorials:

      • Understand the Power of SQL++ to explore different SQL++ queries and experiment with data.

    2. In the tutorial home page, you can do the following:

      • Click Run to execute the example code and generate the response in the Response field.

      • Click Next to go to the next chapter of the tutorial.

      • Click Prev to return to the previous chapter of the tutorial.

      • Select a chapter from the Chapter list to go to a specific chapter.

      • Click Exit Playground to return to the Capella home page.

    To make small changes to the code examples, you must make sure that:

    • Your code examples do not try to access the underlying system resources or resources outside of the Capella network.

    • You keep the semantics of the original code examples.

    Your code examples will not run if they do not meet these requirements.

    Turn Off the Playground

    To turn off the Playground:

    1. Go to Clusters.

    2. Select the cluster you want to turn off the Playground for.

    3. Go to Settings  General.

    4. In the Playground section, select Disable Playground.

    5. Click Save.

    Next Steps

    After you explore the Playground, you can:

    If you want to connect to your cluster:

    1. Generate your cluster credentials to connect and control access to you cluster.

    2. Add your current IP address as an allowed IP for you cluster.

    3. Generate a code snippet to connect your cluster to your application.

    4. Choose and install a Couchbase SDK.

    5. (Optional) Download the security certificate for your cluster and add it to your application’s server machine or IDE:

      1. In the Operational tab, select a cluster.

      2. Go to Settings  Security Certificate.

      3. Click Download.
