Subject DataCenters each with their own local data source
Date Wed, 23 Nov 2011 00:57:09 GMT


I am wondering if Cassandra's features and datacenter awareness can help me with my scalability

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:
- 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?
