Fatal Vs Error

What is the difference between FATAL and ERROR log levels?

      The general description is as follows - FATAL level designates very severe error events that will presumably lead the application to abort. Whereas ERROR/CRITICAL level designate error events that might still allow the application to continue running.

      But, some scenarios where application won't abort can also be considered as FATAL when the availability of that specific functionality is mandatory for completing the task.

An example of a Fatal

      A use case where Database went down in the middle of processing a task can be considered as FATAL if availability of database is mandatory for completion of that task.
