Hi,
I am wondering if Cassandra's features and datacenter awareness can help me with my scalability problems. Suppose that I have a 10-20 Data centers, each with their own local (massive) source of time series data. I would like: - to avoid replication across data centers (this seems doable based on: http://cassandra-user-incubator-apache-org.3065146.n2.nabble.com/Different-KeySpaces-for-different-nodes-in-the-same-ring-td5096393.html#a5096568 ) - writes for local data to be done on the local data center (not sure about that one) - reads from a master data center to any remote data centers (not sure about that one either) It sounds like I am trying to use Cassandra in a very different way that it was intended to be used. Should I simply have a middle-tier that takes care of distributing reads to multiple data centers and treat each data center as its own autonomous cluster? Thanks! Matt
