The Historian Microservice provides a REST API to interact with the HDA (Historical Data Access) services in an OPC UA server. It leverages the OPC Twin API, and invokes these services on the server through the OPC Twin module running on the edge.
The Historian Microservice API is more accessible by surfacing the ExtensionObject encoded HistoryRead/HistoryUpdate payload as first class API parameters.
