Transaction Management in Distributed Database. A distributed system usually exhibits more complexity. Distributed concurrency control - Wikipedia, the free encyclopedia. Distributed concurrency control is the concurrency control of a system distributed over a computer network (Bernstein et al. Weikum and Vossen 2. In database systems and transaction processing (transaction management) distributed concurrency control refers primarily to the concurrency control of a distributed database. It also refers to the concurrency control in a multidatabase (and other multi- transactional object) environment (e. A major goal for distributed concurrency control is distributed serializability (or global serializability for multidatabase systems). Distributed concurrency control poses special challenges beyond centralized one, primarily due to communication and computer latency. It often requires special techniques, like distributed lock manager over fast computer networks with low latency, like switched fabric (e. Infini. Band). SS2. PL provides both the serializability, strictness, and commitment ordering properties. ![]() Strictness, a special case of recoverability, is utilized for effective recovery from failure, and commitment ordering allows participating in a general solution for global serializability. For large- scale distribution and complex transactions, distributed locking's typical heavy performance penalty (due to delays, latency) can be saved by using the atomic commitment protocol, which is needed in a distributed database for (distributed) transactions' atomicity (e. SS2. PL) instead of distributed locking, to achieve global serializability in the entire system. All the commitment ordering theoretical results are applicable whenever atomic commitment is utilized over partitioned, distributed recoverable (transactional) data, including automatic distributed deadlock resolution. Such technique can be utilized also for a large- scale parallel database, where a single large database, residing on many nodes and using a distributed lock manager, is replaced with a (homogeneous) multidatabase, comprising many relatively small databases (loosely defined; any process that supports transactions over partitioned data and participates in atomic commitment complies), fitting each into a single node, and using commitment ordering (e. SS2. PL, strict CO) together with some appropriate atomic commitment protocol (without using a distributed lock manager). See also. Bernstein, Vassos Hadzilacos, Nathan Goodman (1.
