A Transaction Replication Scheme for a Replicated Database with Node Autonomy

Many proposed protocols for replicated databases consider centralized control of each transaction so that given a transaction, some site will monitor the remote data access and transaction commit. We consider the ap preach of broadcasting transactions to remote sites and handling these transactions in their complete form at each site. We consider data of two types: shared-private data and public data and show that transactions working only on shared-private data can be executed under a local concurrency control protocol. We assume a synchronized network with possibilities of partition failures. We show that in our scheme transaction execution can be managed with less communication delay compared to centralized transaction control. 1 Motivation Many replicated distributed database protocols manage the execution of a given transaction at one site, accessing local and remote data copies for its operations, and organize the commit or abort of the transaction from that site. We refer to th...
