Vector v0.13.0 release notes

The Vector team is pleased to announce version 0.13.0!

This release brings a new datadog_logs source to accept logs from dd-agents, a new gcp_stackdriver_metrics sink to send metrics to GCP Stackdriver, and a new subcommand, vector tap that allows for inspecting events flowing out of a component. It also brings a number of smaller enhancements, particularly around the Vector Remap Language used by our remap, filter, and route transforms.

Check out the highlights and changelog for more details.

Highlights

Introducing vector tap

type: new feature domain: graphql domain: cli domain: observability

What’s next

End-to-end acknowledgements
We’ve heard from a number of users that they’d like improved delivery guarantees for events flowing through Vector. We are working on a feature to allow, for components that are able to support it, to only acknowledging data flowing into source components after that data has been sent by any associated sinks. For example, this would avoid acknowledging messages in Kafka until the data in those messages has been sent via all associated sinks.
Mapping and iteration in VRL

Shortly you will be able to iterate over data in VRL to:

  • allow processing of fields containing arrays of unknown length
  • map over keys and values in objects to transform them
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.

This was mentioned in the release notes for 0.11.0, but didn’t quite make it for 0.12 as anticipated. We do expect it to be released in the next few months.
