Getting Started with CockroachDB

By: Kishen Das Kondabagilu Rajanna

Overview of this book

Getting Started with CockroachDB will introduce you to the inner workings of CockroachDB and help you to understand how it provides faster access to distributed data through a SQL interface. The book will also uncover how you can use the database to provide solutions where the data is highly available. Starting with CockroachDB's installation, setup, and configuration, this SQL book will familiarize you with the database architecture and database design principles. You'll then discover several options that CockroachDB provides to store multiple copies of your data to ensure fast data access. The book covers the internals of CockroachDB, how to deploy and manage it on the cloud, performance tuning to get the best out of CockroachDB, and how to scale data across continents and serve it locally. In addition to this, you'll get to grips with fault tolerance and auto-rebalancing, how indexes work, and the CockroachDB Admin UI. The book will guide you in building scalable cloud services on top of CockroachDB, covering administrative and security aspects and tips for troubleshooting, performance enhancements, and a brief guideline on migrating from traditional databases. By the end of this book, you'll have gained sufficient knowledge to manage your data on CockroachDB and interact with it from your application layer.

Performance – Things to consider

In this section, we will discuss general factors related to the infrastructure that affect performance, some standard benchmarking suites, and running a benchmark for your specific needs in CockroachDB.

Infrastructure

It is important to know the ideal configuration for your infrastructure as that significantly influences the performance of CockroachDB that runs on top of it. Here are some key factors to consider in this regard:

  • Central processing unit (CPU): It would be a cliché to say that the CPU plays an important role in performance. We have to ensure each node gets at least four virtual CPUs (vCPUs). You should constantly monitor the CPU usage in all nodes to quickly identify hot nodes that might be receiving more traffic than other nodes. This can make the node's CPU reach its maximum capacity, which can slow down query response times.
  • Memory: Pebble key-value store, table metadata, and CockroachDB internal...
