Journaling


If journaling is needed as part of the business logic, there are better ways than using logging frameworks. The requirements for journaling could be auditing regulations, such as is the case for trading systems.

If the business logic requires journaling, it should accordingly be treated as such - a business requirement. There is journaling technology available that synchronously persists the required information with higher density and lower latency than traditional logging. An example of these solutions is Chronicle Queue, which allows us to store messages with high throughput and low latency.

The application domain could model the information as a domain event and directly persist it into a journaling solution. As mentioned previously, another way is to base the application on an event sourcing model. The auditing information is then already part of the application's model.
