C# 클래스 FoundationDB.Layers.Counters.FdbHighContentionCounter

Represents an integer value which can be incremented without conflict. Uses a sharded representation (which scales with contention) along with background coalescing...

This is obsoleted for most practical purposes by the addition of atomic to FoundationDB v2.x, which do the same thing more efficiently.
