Hatch Evaluation Test
SpringBoot app that read IOT devices data, and process throught a pipeline of REST APIs.
It was based on requirements below: Context
IoT devices send out continuous data which we want to collect (e.g thermostat, heart rate meter, car fuel readings, etc). Your task is to build a pipeline via which we can process the IoT data in a scalable manner. In addition to that, we want to have a secure web service for querying the readings (e.g average/median/max/min values) of specific sensors or groups of sensors for a specific timeframe. We do not expect a production ready system, but it should be a good working prototype. You may use any publicly available open source tools and libraries, but we prefer if the solution is Java/Scala based. Requirements • Simulate data for at least 3 IoT devices which send out a value every second • Scalable and extendable to work with more IoT devices • Fast • Self-contained Your submission should contain the following: o Source code o Short description of the approach and limitations of the implementation o Instructions on how to run and how to access the service Evaluation criteria o Ability to transform vague requirements into a working system o Code quality o Design scalability o Robustness of the implementation
