Servlet 3.1 based Async RT Spring Boot application
This RealTime Statistics API displays the use of Spring Boot and it Scheduling capabilities. It also demonstrates Servlet 3.1 based Asynchronous request processing and friendly error reporting in a REST Api.
GET /statistics
-> provides a transaction summary of the last 60 seconds. It’s calculated in O(1) time & space complexity (‘is constant to the number of secs in a minute’). This can be further improved by using a Min/Max Queue and a always calculated Statistics object of the last 60 seconds (still O(1) complexity). It utilizes Servlet 3.1’s asynchronous request processing capabilities.
POST /transactions
-> create a transaction.
The API supports HATEOAS for seamless discoverability.
