For once, I’m wondering a bit if this post can be helpful to somebody else. I believe my context is pretty specific. Anyway, just in case it might be the case, here it is. My Jet Train project makes use of GTFS. GTFS stands for General Transit Feed Specification. It models public transportation schedules and their associated geographic information. GTFS is based on two kinds of data, static data, and dynamic data. Static data may change but do so rarely, e.g.

Given the trend around microservices, it has become mandatory to be able to follow a transaction across multiple microservices. Spring Cloud Sleuth is such a distributed tracing system fully integrated into the Spring Boot ecosystem. By adding the spring-cloud-starter-sleuth into a project’s POM, it instantly becomes Sleuth-enabled and every standard log call automatically adds additional data, such as spanId and traceId to the usual data. 2016-11-25 19:05:53.
