I’ve got some fun news to start the week off for users of easy-cass-lab: I’ve just released version 5. There are a number of nice improvements and bug fixes in here that should make it more enjoyable, more useful, and lay groundwork for some future enhancements.

  • When the cluster starts, we wait for the storage service to reach NORMAL state, then move to the next node. This is in contrast to the previous behavior where we waited for 2 minutes after starting a node. This queries JMX directly using Swiss Java Knife and is more reliable than the 2-minute method. Please see packer/bin-cassandra/wait-for-up-normal to read through the implementation.
  • Trunk now works correctly. Unfortunately, AxonOps doesn’t support trunk (5.1) yet, and using the agent was causing a startup error. You can test trunk out, but for now the AxonOps integration is disabled.
  • Added a new repl mode. This saves keystrokes and provides some auto-complete functionality and keeps SSH connections open. If you’re going to do a lot of work with ECL this will help you be a little more efficient. You can try this out with ecl repl.
  • Power user feature: Initial support for profiles in AWS regions other than us-west-2. We only provide AMIs for us-west-2, but you can now set up a profile in an alternate region, and build the required AMIs using easy-cass-lab build-image. This feature is still under development and requires using an easy-cass-lab build from source. Credit to Jordan West for contributing this work.
  • Power user feature: Support for multiple profiles. Setting the EASY_CASS_LAB_PROFILE environment variable allows you to configure alternate profiles. This is handy if you want to use multiple regions or have multiple organizations.
  • The project now uses Kotlin instead of Groovy for Gradle configuration.
  • Updated Gradle to 8.9.
  • When using the list command, don’t show the alias “current”.
  • Project cleanup, remove old unused pssh, cassandra build, and async profiler subprojects.

The release has been released to the project’s GitHub page and to homebrew. The project is largely driven by my own consulting needs and for my training. If you’re looking to have some features prioritized please reach out, and we can discuss a consulting engagement.
