NoSQL3
The document discusses the Apache Cassandra NoSQL database. It describes how Cassandra uses keys to store and retrieve data, unlike SQL databases that rely on indexes. Cassandra allows for adding secondary indexes but maintains consistency through a replication technique called versioned clocks. Later versions of Cassandra added features like configurable consistency levels and improved secondary

Autoscaling allows customers to build more cost effective and resilient applications. Using Compute Engine Autoscaling, you can ensure that exactly the right number of Compute Engine instances are available at any given time to handle your applicationâ€™s workload. This saves you money when your applicationâ€™s usage is low, and ensures your application is responsive when utilization is high. Autoscal
