MapReduceNode<'k, 'a, 'b, 's, 'v> (Mibo) | Mibo

MapReduceNode<'k, 'a, 'b, 's, 'v> Type

Namespace: Mibo.Adaptive
Assembly: Mibo.Adaptive.dll
Base Type: obj
All Interfaces: IDisposable , IAdaptiveValue<'v> , IAdaptiveObject , IMapDeltaSink<'k, 'a>

A delta-driven reduction over a map. Keeps a mirror of the source values so removals and updates can invert (sub receives the old mapped value). The mapping is applied per journal element at drain time.
