Design and Development of Student Activity Record Systems Using the Concept of Reactive Streams in Data Stream Processing

Abstract Student Activity Record System is an elearning module that is used to record student activities in the context of behaviour assessment. Student and teacher sent datas in the form of photos, videos, texts and geolocation coordinates. With the number of requests sent by the user, the load from the server side will continue to gain weight. It requires an efficient way to use the resources on the server side, namely Central Processing Unit and memory. The using of Netty as an asynchronous event driven web server and the reactor libraries as a reactive streams implementation on the server side become the right choice to optimize Central Processing Unit and memory usage. This research emphasizes the design of system architecture and library selection that implements the concept of reactive streams on the client-server side. The reactive streams concept is applied to web dashboard and mobile application so that web and mobile application become more responsive because execution is asynchronous.
