About this Hands-on Lab

Sometimes data is relatively straight-forward — there’s just an overwhelming amount of it. That’s exactly what Cloud Bigtable is meant for. Cloud Bigtable is a fully managed NoSQL database service designed to handle massive amounts of information. In this hands-on lab, you’ll configure database instances and clusters for Cloud Bigtable in the console and then use command line `cbt` commands to create a schema and populate the table with data.
