Sorry guys, that was meant to be private. My opinion stands, but I didn't want to hurt any of the dev's feelings by being too frank. I think the progress has been good in new features, but I feel we have taken a step back in relability and scalability since so many features were added without adequate testing. Hopefully, at some point soon, it will get better and doing a data import job won't take a cassandra cluster to it's knees or we won't experience stop the world GC issues and have out of memory errors from routine usage.
