Spring off the HTTP High Dive into an Optimized Connection Pool

Track: Frameworks
In this session, I will explore different Spring libraries used for HTTP calls like RestTemplate, WebClient, and RestClient-which is a new feature in Spring Framework 6.1. I’ll then dive into the multitude of settings that are available along with what defaults are present when nothing is given, focusing in on connection pool settings. I’ll use observability tools and logs to show what’s happening under the covers and showcase some gotchas for things like TTL settings and DNS caching.
