Demo: Diligent — An OSN Data Integration System Based on Reactive Microservices

This demo showcases some of the capabilities of Diligent, a platform for collecting and analysing data from Online Social Networks and is still under development. Diligent relies on microservices and reactive streams, which optimize the time spent (t), to the resources used (r), ratio (t/r). The proposed demo will present: - The vast hardware utilization margins produced by using both blocking and reactive I/O approaches. - The performance gap between using blocking I/O and Reactive I/O clients. Both experiments highlight the added benefits of using reactive approaches in online social network data processing systems.
