Data reorganization in a dynamically reconfigurable environment

The authors consider data reorganization in a dynamically reconfigurable distributed database system. The network environment they study is a dynamic system prototype called Driftwood. They present reallocation strategies corresponding to different network reconfiguration and then address the nonblocking reorganization approach. They cover the implementation strategies, impact on user transaction processing, and efficiency. The authors present an algorithm to construct a parallel reorganization scheduler that is expected to minimize the system recovery time
