If people are using Cassandra already why not just use Titan? If it's built on top of something you're already maintaining why not. It make sense. GraphX last

If people are using Cassandra already why not just use Titan? If it's built on top of something you're already maintaining why not. It make sense. GraphX last I check was in beta, at least last databrick meetup stated so. GraphX would make sense if you're stack is cassandra + spark. For me personally, I have time to wait to see if Flink will mature and interop with Cassandra before I invest my time in Spark or Flink (or both if I have the luxury).
