Lesson 56 - The Ambulance Pattern    
(posted April 8, 2019)

The ambulance pattern is useful for creating a “fast-path” for requests that need to go ahead of others - just like cars pulling over to let an ambulance through (hence the name of the pattern). In this lesson Mark Richards explains why message priority is not a good way of implementing this pattern, and shows another technique that is much more effective for implementing this pattern.
