Analyzing consistency properties for fun and profit

:  Analyzing Consistency Properties for Fun and Profit Wojciech Golab, Xiaozhou Li, Mehul A. Shah HP Laboratories HPL-2011-6 data consistency, algorightms, key-value stores Motivated by the increasing popularity of eventually consistent key-value stores as a commercial service, we address two important problems related to the consistency properties in a history of operations on a read/write register (i.e., the start time, finish time, argument, and response of every operation). First, we consider how to detect a consistency violation as soon as one happens. To this end, we formulate a specification for online verification algorithms, and we present such algorithms for several well-known consistency properties. Second, we consider how to quantify the severity of the violations, if a history is found to contain consistency violations. We investigate two quantities: one is the staleness of the reads, and the other is the commonality of violations. For staleness, we further consider tim...
