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 types. Looking forward to testing these new forks.
