VersionVector

data class VersionVector(val vectorMap: MutableMap<String, Long> = mutableMapOf())

VersionVector is a vector clock used to detect relationships between changes, determining whether they are causally related or concurrent. It is similar to vector clocks but synced with the Lamport timestamp of the change.
