Just to be clear, the criticism is of Redis Cluster, which has been redesigned because the first design was so lax it was effectively unusable. The real issue, is that as of right now I have no idea what the exact semantics and failure conditions of Redis cluster are. I'm not clear that anyone really knows. Salvatore thinks he knows, but we can't be sure that he does. With all this talk of practicality, what really makes distributed systems practical is when someone can do a formal analysis of them and conclude what possible states can occur in the system. This is not work that database users should do, it is work that database implementors should do. The failure to use a known consensus system is a failure to deliver a database I can understand. I find this all a bit disappointing since I've been a huge fan of Redis since the early days. It's an amazing tool that I still have in production, but I get the feeling that it's utility will never expand to suit some of my larger needs. Bummer. |
