MuleSoft came up with Mule 4, its latest non-blocking runtime engine built with cutting edge reactive-programming a couple of years ago. It is a fundamental shift in how ESBs have been built and how they operate.
With this paradigm shift in architecture and design of Mule 4 from its erstwhile predecessor, Mule 3, there is curiosity around when to Migrate, what to consider and how to approach it.
This session of MuleSoft meetup will give you a perspective of what is fundamentally different/new and how to approach this change at your organization.
