ADR-0005 Change ResponderManager to a simple case class

Date: 2022-06-06

Status

Accepted

Context

The org.knora.webapi.responders.ResponderManager was implemented as an Akka-Actor.

Decision

In preparation of the move from Akka to ZIO, it was decided that the ResponderManager is refactored using plain case classes.

Consequences

The actor messages and responses don't change. All calls made previously to the ResponderManager and the StorageManager are now changed to the ApplicationActor which will route the calls to either the ResponderManager or the StorageManager based on the message type. The ApplicationActor is the only actor that is allowed to make calls to either the ResponderManager or the StorageManager. All requests from routes are now routed to the ApplicationActor.
