Re: Convert single node C* to cluster (rebalancing problem)

Re: Question: Large partition warning

fyi ticket already existed for this, I've submitted a patch that fixes this specific issue but it looks like there are a few other properties that will suffer from the same. As I said on the ticket, we should probably fix these up even though setting things this high is generally bad practice. If

Cassandra cost vs an RDBMS?

A client recently inquired about the costs of running Cassandra vs a traditional RDBMS like Postgres or Mysql, in the cloud. They are releasing a b2b product similar to Slack, Trello, etc which will have a free tier. And they're concerned about the costs of running it on Cassandra, and whether it
