The Vector team is pleased to release 0.9.0. This is a initial dev release. Checkout the Highlights, Changelog, and What's Next section for more detail.
Highlights
Breaking Changes
The `gcp_stackdriver_logging` sink has been renamed to `gcp_stackdriver_logs`
This brings the sink naming inline with consistent naming patternThe `elasticsearch` sink `compression` option now defaults to `none`
Compression is not supported by all Elasticsearch service providersACL is now optional for the Google Cloud Storage sink
ACL is not always required when creating objects in GCP Cloud StorageEnhancements
New Encoding Options
Vector now lets you whitelist, blacklist, and format fields when events are encodedLua Transform v2
The next iteration of our Lua transform.Improved Shutdown
A faster and more reliable shutdown processNew Features
À La Carte Custom Vector Builds
Build Vector with select componentsNew Dedupe Transform
Shed duplicate logsNew Tag Cardinality Limit Transform
Protect downstream metrics storages from runaway metrics tagsNew Filter Transform
Filter and route your logs based on defined conditions4 New Sinks!
Papertrail, Honeycomb, Pulsar, and DataDog Logs

What's Next
Kubernetes!
We're doing this integration right. We've been alpha testing with a number of large clusters and we've honed in on a very high-quality approach that reflects the UX Vector is going after. You can learn more in our Kubernetes Integration RFC. Feedback is welcome!
WASM Driven Plugin Architecture
This release included an overhaul of our
luatransform, which represents a big step towards making Vector more flexible. Lua is an excellent language when you need some quick scripting capabilities. But what if you need something more powerful? Like writing your own custom source, transform, or sink? Vector plans to solve this with WASM foreign module support, enabling you to extend Vector in the language of your choice with little performance penalty. ❤️ WASM. Check out the WASM Foreign Module Support RFC for more info.Dynamic HTTP Rate-Limiting (AIMD)
Fiddling with rate-limits is a frustratin endaevor. If you set them too high you risk overwhelming the service; too low and you're unecessarily limiting throughput. And what happens if you deploy a few more Vector instances? Vector is planning to solve this by automatically detecting the optimal rate limits, taking inspiration from TCP congestional control algorithms. Check out the Dynamic HTTP Rate Limiting RFC.
Vector Observability
Did you know this release includes a new hidden
internalsource that emits metrics reflecting Vector's own internal state? 👀 We didn't highlight this source because we have not finished instrumenting Vector and we'll be changing the internal schema used.Fun fact, we took an event-driven approach to Vector's internal observability, which we strongly beleive in. We want Vector to be a good example of our own advice. Checkout the Event-Driven Observability RFC.
The Vector roadmap is publicly available and represents forward looking progress. Vector is open-source and community driven. Your feedback is welcome!
