Reading Data from Cloud Bigtable with Cloud Functions

About this Hands-on Lab

Cloud Bigtable can store petabytes of data — and Cloud Functions can access any of that data, parse it, and send it on to another service. In this hands-on lab, you’ll first create a Bigtable instance as well as a table and populate it with test data. Then you’ll build an HTTP-triggered Cloud Function to read specific elements of that data and output it for verification.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Enable APIs: Enable the APIs necessary for creating a Cloud Function.
Create and Prepare the Cloud Bigtable Instance: Create a Cloud Bigtable instance and then connect to it in the Cloud Shell so that you can create a test table and populate it with sample data.
Retrieve the Working Files: Clone a Github repository to access the source files for the Cloud Function.
Create and Test the Cloud Function: Create, deploy, and test a Cloud Function, triggered by HTTP, to read and output selected data from Cloud Bigtable.

Additional Resources

In this scenario, your team is tracking the hold status of a set of objects in a particular Cloud Storage bucket and wants to be notified if the status changes. You decide to set up a Cloud Function that will write an entry to the log when triggered by a change to the metadata that outputs the current hold status.
