SESSION + Live Q&A
Observability, Event Sourcing and State Machines
What is a way to have complete transparency of the state of a service? Ideally we would record everything - the inputs, outputs and timings - in order to capture highly reproducible and transparent state changes. However, is it possible to record every event or message in and out of a service without hurting performance? Join Peter for an exploration of the use cases and practicalities for having downstream services consuming all of the state changes of an upstream service in order to provide automated, real-time insight of services.
