What’s CockroachDB?
(taken from the CockroachDB FAQ)
CockroachDB is a distributed SQL database built on a transactional and strongly-consistent key-value store.
It scales horizontally; survives disk, machine, rack, and even datacenter failures with minimal latency disruption and no manual intervention; supports strongly-consistent ACID transactions; and provides a familiar SQL API for structuring, manipulating, and querying data.
CockroachDB is inspired by Google’s Spanner and F1 technologies, and it’s completely open source.
What’s this Guide For?
This guide explains how to set up a demonstration/evaluation CockroachDB cluster using a single VirtualBox virtual machine to run 3 CockroachDB database nodes.
It uses a pre-built VirtualBox image as a starting point to create the guest machine.
You’ll need to be connected to the Internet to build this machine as it requires you to download and install some things but you don’t need to be online to run the CockroachDB cluster.
What you’ll Need
The detailed requirements are in the guide but in summary you will need:
-
A Windows, Mac, or Linux computer, connected to the Internet, with at least 10Gb of free space.
-
Excluding the download time and depending on your experience level, it should take you about 20 minutes to get a 3 node CockroachDB cluster running on a freshly created VirtualBox virtual machine.
