Please tell me how to add these services based on the current code structure？

Thank you very much for sharing about DDD.
In actual projects, it is often necessary to start one or more background services to synchronize the database cache and check the status to ensure that the service is available.
Please tell me how to add these services based on the current code structure.
Best wishes.😀😀

Hi @pfeak, if the the cache is specific to the DB implementation (e.g. Postgres) then I'd put it close to the postgres implementation in the infrastructure layer, e.g. here.
