Dear folks, Background: I'm leaning Kafka stream and want to use that in my product for real time streaming process with data from various sensors.
Question: 1. Can I define my own processing function/api in Kafka stream except the predefined functions like groupby(), count() etc.? 2. If I could define my own function, could you please specify a example or introduce me a github project for example? Thank u in advance! Regards, Long Tian
