Custom Component FAQs
How do custom Vespa components impact performance?
Custom components are compiled and run natively within Vespa's JVM, so they typically have minimal performance overhead compared to Vespa's built-in components.
What languages can I use to extend Vespa?
Vespa components are typically written in Java, but you can also use other JVM languages like Kotlin or Scala.
Can custom components be updated without downtime?
Yes. Vespa supports hot reloading of components. With proper versioning and deployment practices, updates can be rolled out with zero downtime and no query interruption.
Do custom components work in both self-hosted Vespa and Vespa Cloud?
Yes, custom components work in both environments, though Vespa Cloud has additional security and testing requirements.
How complex is it to maintain custom components?
Maintenance complexity depends on the component, but Vespa's stable APIs minimize breaking changes. Our expertise helps ensure sustainable, future-proof implementations.
