Exercise: Take a KillrVideo Tour

In this exercise, you will:

  • Take a brief tour of the KillrVideo website - which you will build in this course

  • Get a sense of the skills you'll learn in this course

  • Become generally enthusiastic about this course and its fine instructors

Welcome to the AppDev with Cassandra training session using DataStax Apache Cassandratm as a Service (CaaS). In this course you will spin up your own database, connect to it using the DataStax Driver, and implement functionality in the video sharing website killrvideo.com. You will see that connecting your application to a Cassandra database is a snap, and querying and mutating data with the driver is simple to do.

Let's get started!

Steps

1. Open your KillrVideo instance. In a new tab in your browser, paste in the KillrVideo IP address you received for this course.

 2. Inspect the landing page. A quick look at the landing page (and the "LOADING..." message alerts you that your instance of KillrVideo doesn't look like the official killrvideo.com site the instructor showed you.

There are two reasons why your instance isn't fully functional:

  • First, the back-end service for your KillrVideo instance is not yet running.
  • Second, Even if your back-end service were running, it's not fully functional yet - That's what you get to build in this class!

However, there are some things we can investigate in our own instance of KillrVideo...

3. Start a tour. One of the things you can do with your instance of KillrVideo is to follow the online tour. Start by clicking the Tour Off button on the top of the window:

4. Continue the tour. We'll only take a couple steps into this tour right now. We just want you to be aware of it.

5. Leave the tour. Now that you have seen how to follow the tour, we'll leave off here. You can come back and follow the tour later. It's a great way to see the KillrVideo data model and some of the interesting use-cases contained within KillrVideo.

6. Try to register. Eventhough we realize the functionality is missing, let's try to register just to see what happens. Click on the REGISTER button in the top-right corner of the window, fill out the form and click Register.

 

7. Regain your composure. Yeah, registration didn't work - but that's actually a good thing. Fixing the identity management service is what we will learn how to do in this course!

8. Launch Studio. Now let's familiarize ourselves with DataStax Developer Studio. Your database machine(s) hosts the Studio application. This application let's you access your Cassandra database via notebooks - we'll show you...

Back in the Apollo tab, click on Launch Developer Studio.

9. Look for the notebook. Here is the notebook you are looking for (if you don't see it, refer to the next section):

If you cannot find this notebook, you can download it here, and then import the notebook into Developer Studio.

10. Open the notebook. Click on the notebook to open it.

11. Fill in Connection credentials. The first time you open the notebook, you will be prompted for the Connection credentials. Fill in the credentials as shown (KVUser and KVPassword). Then, click the Test button to make sure the credentials work. Once you have verified the credentials, click Save.

12. Work through the notebook. This notebook explains how to use studio. Either with your instructor, or individually, follow the exercises in the notebook. Once you have completed this notebook, you have completed this exercise!

Woohooo!!! You have your very own full Cassandra database spinning-up! Proudly let your friendly neighbors know you beat them. This isn't a race, but let's see if you finished first.
