Title: On Quantitative Metrics for the Consistency and Availability in Distributed Databases
Abstract: This article considers simultaneous attainability of consistency and availability. The approaches to determining the maximum possible levels of accessibility for different consistency models are compared. The necessity of introducing quantitative metrics for these two indicators and review the prior articles with quantitative estimates of consistency is advocated. The importance of this problem is confirmed, and directions for modeling the parameters of the applied problem using numerical experiments are proposed.
