Interference-Free Checkpointing Algorithm for Distributed Database System
Chaojin Luo · 2012
Checkpointing Algorithm is widely used in distributed database system (DDBS) to recover DDBS from fault. In traditional algorithms, normal DDBS activities, i.e. message exchanging between distributed sites should be blocked in checkpointing, thus the DDBS service are interfered with and the DDBS availability is dropped down. This paper presents a new algorithm that does not impact DDBS normal processing in checkpointing, and hence promote the DDBS availability.
