Welcome to our ongoing series of post on our experiences in using Istio during the development of Vamp Lamia.
In our previous post, we presented Vamp Lamia’s approach to A/B testing and then delved deeper into how Experiments use Welch’s t-test to identify the test’s winner in a statistically sound way.
In both scenarios, however, we relied solely on Elasticsearch to gather the necessary statistics to calculate the A/B test outcome. This begs the question: what if we wanted to use a different source? In this post we will discuss the possibility of employing a custom data source, be it a different database or another application, deployed inside or outside the cluster.
