Three Incidents Later: Why We Turned Virtual Threads Off

Speaker: Jakub Coufal - Software Engineer at SentinelOne (https://www.linkedin.com/in/coufalja/)

Abstract:

Virtual threads arrived in Spring with a compelling pitch: flip a Spring Boot property, get massive concurrency for free. Several teams took that literally and enabled them across all services by default. This talk is what happened next.

Jakub also added when we chatted about this:

Subtitle could be:

A production post-mortem on Spring Boot, Java 21, and the "free lunch" that it wasn't

Which is really compelling. Virtual threads are a great technology, but the limitations are still there. This will definitely be a very interesting talk, and I personally look forward to the discussion it will spark.
