Sharding monotonic
WebbMonotonic reads is a client-centric consistency model which ensures that if a process has seen a particular value for the object, any subsequent accesses will never return any previous values. Monotonic reads are used in several applications like news feeds and social networks to ensure that the user always has a forward moving view of the data. Webbmonotonic reads is applied on shards. The decision to explore monotonic reads versus the broader area of client-centric consistency was taken to reduce scope, redundancy and …
