- /' Brief Summary of my comprehension:
- Publisher will stream data into designated database.
- Consumer will subscribe to publisher in order to have the same set of data.
- Participant perform query for database2 from the consumer side but didn't
- get what they want.
- So participant send error message to help desh ,presumably an observable that
- broadcaast error notification to whomever that has subscribe to it.
- So helpdesk stream the error notification to one of it's subscriber, in this
- case, it's the message auditor, aka Auditor.
- Auditor can either go check at the database, or check the publisher and
- consumers themselves, provided if there's a logic for that to see what went
- wrong. In this case, we are dealing with loss of data transmission, so
- auditor will acquire the information of the missing data and send the
- error message to publisher to retransmit the data again to the consumer
