What’s next

Enabling Adaptive Concurrency Control by default

We released Adaptive Concurrency Control in version 0.11.0 of Vector, but, up until now, this feature has been opt-in. We’ve been collecting user feedback, making enhancements, and expect to enable this feature as the default in 0.17.0. Users will still be able to configure static concurrency controls as they do now.

This was previously scheduled for 0.16.0 but we wanted to allow more time for testing the feature.

Kubernetes aggregator role

We are hard at work at expanding the ability to run Vector as an aggregator in Kubernetes. This will allow you to build end-to-end observability pipelines in Kubernetes with Vector. Distributing processing on the edge, centralizing it with an aggregator, or both. If you are interested in beta testing, please join our chat and let us know.

We do expect this to be released in 0.17.0.
