Distributed concurrency control with limited wait-depth
Abstract
Distributed wait-depth-limited (DWDL) concurrency control, a locking-based method that limits the wait-depth of blocked transactions to one, which assures that deadlocks are resolved as part of regular transaction processing is described. The performance of DWDL is compared with that of distributed two-phase locking (2PL) and the wound-wait concurrency control method through a detailed simulated. Results show that DWDL behaves similarly to 2PL for low data contention levels, but at high lock contention levels, DWDL outperforms the other methods to a significant degree.
