Version Vectors

In my last article, we talked about Vector Clocks. We learned that Vector Clocks could help establish the ordering of operations, including identifying whether operations happened concurrently or were causally related. A very similar mechanism is used by Version Vector, but it’s used for a slightly different purpose.

Version Vector

Version Vectors are generally leveraged in distributed data-driven applications, where each data record is tied to a Version Vector. Since it’s a distributed system, a data record can be updated concurrently by multiple nodes. Thus, we can…
