Thank you for useful article @Bryan Bende, After reading your post, I confuse some points that HOW and WHERE to configure properties: Max Batch Size, Max Size of Message Queue, Max Size of Socket Buffer. My flowfile: Data Producer --> JettyWebsocketServer --> ListenWebsocket --> Flowfile So I don't know how and where to configure above properties. Where is Message Queue between Channel Reader and Listen Processor? I just only configure JettyWebsocketServer(Input Buffer Size, Max Text Messsage Size) and ListenWebsocket has no properties relating to Queue Size. Thanks, ... View more
