In computer science, a timestamp-based concurrency control algorithm is a non-lock concurrency control method. It is used in some databases to safely handle transactions, using timestamps. See more Assumptions • Every timestamp value is unique and accurately represents an instant in time. • A higher-valued timestamp occurs later in time than a lower-valued timestamp. See more • Multiversion concurrency control • Timestamping (computing) See more Note that timestamp ordering in its basic form does not produce recoverable histories. Consider for example the following history … See more Timestamp resolution This is the minimum time elapsed between two adjacent timestamps. If the resolution of the … See more
