What reasons make error transmission between components prohibited in high-load systems?

In high-load systems, error transmission between components is often prohibited or limited for several reasons:

• Failure isolation: If an error is transmitted directly, it can cause a chain reaction and lead to a system failure. Isolation allows localizing the problem.
• Performance: Processing and transmitting errors require resources. In high-load systems, excessive error transmission can slow down operations.
• State management: Errors may contain sensitive data or unstable states, the transmission of which can lead to incorrect operation of other components.
• Debugging complexity: With many components and errors, it is difficult to trace the source of the problem if errors are freely transmitted.

Therefore, such systems usually employ mechanisms for local error handling, logging, and centralized monitoring, rather than direct transmission of exceptions or errors between components.
