Task 16 – Implementing SQLSportTrackerMotivation
In this task, we will explore the benefits that SQL DSL brings us when it comes to more complex pipelines that are composed of several aggregations, joins, and so on. Again, as a recap, let's restate the problem definition.
Problem definition
Given a GPS location stream per workout (the same as in the previous task), create another stream that would contain information if the runner increased or decreased pace in the past minute by more than 10% compared to the average pace over the last 5 minutes. Again, use SQL DSL as much as possible.
The test and deployment are the same as in the corresponding SportTracker task, so we will skip this here. Instead, we will demonstrate how SQL (and schemas) can help us when we are dealing with joins – which is what we did when we were implementing our SportTrackerMovation example. So, let's reimplement that as well!
