HARNESSING THE POWER OF OPENTELEMETRY FOR REAL-TIME CONTINUOUS FEEDBACK - Roni Dover

What do you know about the code changes that were just introduced into the codebase? When will you start noticing if something goes wrong? If there are so many accessible observability sources that can tell us what the code is doing, why are we using so little of that in our day-to-day coding?

Continuous Feedback is a new dev practice that aims to make practical usage of code runtime data to shorten the feedback loop during development. It enables developers to get early data about their code changes and detect issues and regressions as-they-code. At the same time, collecting data from multiple environments, allows developers to instantly understand how their code is performing in the real world. In this session, we'll look past the novelty of using OSS observability tools and technologies, to discuss how we can actually make them useful for developers. We'll take a look at the benefits of enabling OpenTelemetry collection for dev and test data and examine OSS tools to help analyze the application runtime.

Throughout the talk, we'll go over code examples of common anti-patterns, code smells, hidden errors, and other types of problems that observability can reveal.
