Easy Cassandra Stress (easy-cass-stress) Tool

easy-cass-stress tool for stress testing Apache Cassandra clusters

In this course we will download/compile and execute several workloads using easy-cass-stress tool for generating a lot of load on our Apache Cassandra clusters.

We will review the documentation and all available options for easy-cass-stress tool.

We will execute many workloads using easy-cass-stress tool.

We will understand how to extract metrics from easy-cass-stress workload executions.

Short excerpt from easy-cass-stress tool documentation :

easy-cass-stress is a workload-centric stress tool for Apache Cassandra, written in Kotlin. Workloads are easy to write and because they are written in code. You have the ultimate flexibility to build whatever you want without having to learn and operate around the restrictions of a configuration DSL. Workloads can be tweaked via command line parameters to make them fit your environment more closely.

One of the goals of easy-cass-stress is to provide enough pre-designed workloads out of the box, so it’s unnecessary to code up a workload for most use cases. For instance, it’s very common to have a key value workload, and want to test that. easy-cass-stress allows you to customize a pre-configured key-value workload, using simple parameters to modify the workload to fit your needs.

The tool is flexible enough to design workloads which leverage multiple (thousands) of tables, hitting them as needed. Statistics are automatically captured by the Dropwizard metrics library.
