Is that possible to provide a substitute option for replacing all Java components? Because if one company writes all its products in Go, the best option for them is their developer can understand all the components behind their system, and if facing some problems they are required to know how to modify the source code and handle the problem. This IM system already includes MySQL MongoDB(which is written in C++), and OpenIm component written in Go, and Kafka written in Java, and desktop and mobile written in vue (javascript, typescript html css )and flutter (dart) and Android SDK write in java and ios sdk write in object-c, and it require to hire many developers with experience in different languages for future develop）
