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.

Execution of a SQL query

Any application that talks to CockroachDB can use Postgres-compatible drivers to talk to CockroachDB. If you prefer object-relational mappers (ORMs), Golang ORM (GORM), go-pg, and SQLBoiler can be used to interact with CockroachDB. Irrespective of where the actual data resides, you can issue a query to any of the nodes in the cluster. Whichever node the query lands in, that node acts as a gateway.

Requests from SQL clients are received as SQL statements. The SQL layer is responsible for converting these SQL statements into a plan of key-value operations and passing it to the transaction layer. CockroachDB, as of version 21.2, supports both native drivers and the Postgres wire protocol. A wire protocol defines how two applications can communicate over a network.

CockroachDB has support for most American National Standards Institute (ANSI) SQL standards to change table structures and data. Next, we will look at the various stages of query execution.
