create topologies. New components are often done in an interface way. In contrast, declarative API operations are defined higher-order functions. It allows us to write function code with abstract types and methods, and the system creates the topology and optimizes the topology. Declarative APIs often also provide more advanced operations (such as window functions or state management). The sample code will be given shortly after. The Mainstream stream processing system has a range of implementa
