MDC (*mapped diagnostic context*) is a way to attach thread-scoped named identifier that can be added to every log message from that thread.

It is used to provide log messages with information that is unavailable to the scope when log is written.It provides the thread and user context to log messages and hence stamp each log for better tracking.

For example, it can help put Correlation Id to a request’s logs to help filter it out from similar logs at that time (from other quests) and also track it easily when this request hop from service to service by sharing the Correlation Id.

Typical use cases
