This document discusses Windows Azure Table, a NoSQL distributed storage system for structured data in Windows Azure. It provides scalability and availability similar to BigTable and SimpleDB. The Azure Table uses the CAP theorem allowing for high availability and partition tolerance over consistency under network partitions. It also supports OData protocols and can scale to millions of requests per second across hundreds of instances for high performance applications.
