The best thing about this product was how easy it made setting up my environment with multiple nodes across different regions (US West/East). It's also very well documented which makes troubleshooting issues much easier than other products I've used previously where documentation wasn't as detailed nor available online to search through like here at Github! There really isn’t anything bad so far but there are some things we would have liked if they had implemented them sooner such has better support of SASL authentication when using LDAP instead only supporting Kerberos over TLS connections currently out from version 1.* onwards - though not sure what their reasoning behind doing away wth sasl auth completely? We needed something reliable yet scalable enough since our workloads were growing rapidly requiring more resources per node within each region too keep everything running smoothly & cost effective all around.
