PharmaxoScientific.MessageDispatch.Snapshotting

A package that provides a composable IDispatcher<ResolvedEvent> that can be used to conditionally snapshot the current state of the system.

Included:

• ISnapshotStrategy - an interface that can be implemented to define when a snapshot should be recorded by the dispatcher
  • IntervalSnapshotStrategy, OnceDailySnapshotStrategy, and NamedEventSnapshotStrategy are provided as ready made implementations
• IStateProvider - an interface that should be implemented by a class that provides the current state that should be persisted when a snapshot is recorded
• IStateSnapshotter - an interface that can be implemented to define how to save and load snapshots
  • ProtoBufStateSnapshotter and JsonSerialisingFileStateSnapshotter are provided as ready made implementations
• SnapshottingResolvedEventDispatcher - a dispatcher that is composable from the above, which dispatches ResolvedEvents to an inner dispatcher and conditionally triggers a snapshot of the current state to be recorded
