Open-Source

easy-cass-lab now available in Homebrew

I’m happy to share some exciting news for all Cassandra enthusiasts! My open source project, easy-cass-lab, is now installable via a homebrew tap. This powerful tool is designed to make testing any major version of Cassandra (or even builds that haven’t been released yet) a breeze, using AWS. A big thank-you to Jordan West who took the time to make this happen!

What is easy-cass-lab?

easy-cass-lab is a versatile testing tool for Apache Cassandra. Whether you’re dealing with the latest stable releases or experimenting with unreleased builds, easy-cass-lab provides a seamless way to test and validate your applications. With easy-cass-lab, you can ensure compatibility and performance across different Cassandra versions, making it an essential tool for developers and system administrators. easy-cass-lab is used extensively for my consulting engagements, my training program, and to evaluate performance patches destined for open source Cassandra. Here are a few examples:

Cassandra Secondary Index Preview #1

If you’ve looked into using Cassandra at all, you probably have heard plenty of warnings about its secondary indexes. If you’ve come from a relational background, you may have been surprised when you were told to create multiple tables (materialized views) instead of relying on indexes. This is because Cassandra is a distributed database, and the impact of doing a query that hits your entire cluster is you lose your linear scalability. If you’re capped at 25K queries per second per server, it doesn’t matter if you have one or a thousand servers, you’re still only able to handle 25k queries per second, total.
