I have been asked so many times about DataWeave Performance during my project work. This is because developers try to find arguments to not use it when they realize that a new and proprietary programming language is introduced. Most of the time they have the same “natural response” of resolving the problem by going to the known and comfortable zone called “Java.”
This video post will try to answer the performance question and give a set of basic and solid arguments to define the correct choice between DataWeave, Java custom code, and Mule Default Transformers to perform data transformations.
