Implementations
This is an SPI, and the framework provides several implementations.
| If multiple implementations of this service are registered, all will be called. |
Applib (Log4j2)
The applib provides a simple implementation, CommandLogger, that just logs events as they are received.
Command Log
The Command Log module also provides an implementation, CommandSubscriberForCommandLog. This implementation persists an instance of the CommandLogEntry entity for each event.
