Interface HistoryService

public interface HistoryService

Service exposing information about ongoing and past process instances. This is different from the runtime information in the sense that this runtime information only contains the actual runtime state at any given moment and it is optimized for runtime process execution performance. The history information is optimized for easy querying and remains permanent in the persistent storage.
