Hey Jon,

It's awesome to see that you're reviving both these projects!

I was eager to get my hands on an updated version of tlp-cluster with up to
date AMIs 🎉
tlp-stress is by far the best Cassandra stress tool I've worked with, and I
recommend everyone to test easy-cass-stress and build additional workload

Looking forward to testing these new forks.

> This is a powerful tool that makes it much easier to spin up lab
> environments using any released version of Cassandra, with functionality
> coming to test custom branches and trunk.  It's a departure from the old
> tlp-cluster that installed and configured everything at runtime.  By
> creating a universal, multi-version AMI complete with all my favorite
> debugging tools, it's now possible to create a lab environment in under 2
> minutes in AWS.  The image includes easy-cass-stress making it
> straightforward to spin up clusters to test existing releases, and soon
> custom builds and trunk.  Fellow committer Jordan West has been working on
> this with me and we've made a ton of progress over the last several weeks.

> GH repo: https://github.com/rustyrazorblade/easy-cass-lab
> I hope you find these tools as useful as I have.  I am aware of many
> extremely large Cassandra teams using tlp-stress with their 1K+ node
> environments, and hope the additional functionality in easy-cass-stress
> makes it easier for folks to start benchmarking C*, possibly in conjunction
> with easy-cass-lab.
> Looking forward to hearing your feedback,
