Hi there, I'm making research to find right solution for our needs. We need persistent layer for groups of social network. These groups will have big amount of data ( ~100 GB) - users profiles, their activities and etc. And all job with these entities should be make online - user can ask to unsubscribe him, or connect another users to him. So we'll work with small pieces of big dataset not big data in offline - like log parser. We wants to have ability to make search of different table attributes and of course scalability and failover. We need easy add/remove nodes in cluster without stopping entire system.
All of this can be done with Amazon SimpleDB but we don't want to depend on external service. That's why we're looking for some 3d product. We have such candidates: - HBase - - CouchDb - HyperTable - Own bicycle Can you tell me is HBase will work for such system? If we have 2 or 3 data centers and we loose connection between them - what behavior of HBase will we see ? And when we restore connection in 1-2 hours - what should we expect from HBase ? Thank you.
