Synchronizing distributed transactions

Definition

Distributed concurrency control provides concepts and technologies to synchronize distributed transactions in a way that their interleaved execution does not violate the ACID properties. Distributed transactions are executed in a distributed database environment, where a set of connected data servers host related data. A distributed transaction consists of a set of subtransactions, each of which is executed by one data server. Distributed concurrency control makes sure that all subtransactions of a set of distributed transactions are serialized identically in all data servers involved. Therefore, not only local dependencies need to be taken into account, but also dependencies involving multiple data servers. Concurrency control techniques known from centralized database systems need to be extended to cope with the new requirements imposed by the distribution aspect.
