Vector v0.8.0 Release Notes

A wholesome platter of features,
The easiest way to stay up-to-date. One email on the 1st of every month. No spam, ever.

The features for this release have been pouring in. Clearly the Vector team need better hobbies.

We're excited to release Vector v0.8.0! Vector follows semantic versioning, and this is an initial dev release. This release brings 14 new features, 24 enhancements, 11 bug fixes. Checkout the highlights for notable features and, as always, let us know what you think!


Automatically Merge Split Docker Events!

Anyone that was worked with Docker logs knows how frustrating this problem can be. Docker, by default, splits log messages that exceed 16kb. While 16kb seems like a lot, it can easily be exceeded if you're logging rich structured events. This can be a very difficult and frustrating problem to solve with other tools (we speak from experience). In this release Vector solves this automatically with a new `auto_partial_merge` option in the `docker` source.

We love assimilation and look forward to a future where our individualistic human personalities can also be merged into a societal hive mind.

Improved Control Flow With Swimlanes

The new swimlanes transform makes it much easier to configure conditional branches of transforms and sinks. For example, you can easily create if/else pipelines.

Remember to occasionally let your branches mingle so that they don't completely lose touch.

Config Unit Test Improvements

Unit testing your configuration files has been supported by Vector for a while now. Based on feedback we've received and some healthy dog-fooding we've expanded their functionality and made a lot of improvements to how they work.

If you aren't yet using unit tests in your configs we strongly recommend you try it out. You can find out more in this guide.

Custom Field Schemas

Not everyone enjoys Marmite, we get it, some people have wrong different tastes. Similarly, not everyone is going to want to follow our default field schema (`host`, `message`, `timestamp`). Rather than making you work around this with transforms we've added some handy global options to set these universally:

# OPTIONAL - Log schema
  host_key = "host" # default
  message_key = "message" # default
  timestamp_key = "timestamp" # default

Support for Multiple Config Files

Vector is now able to execute a topology spread across multiple config files, which allows you to break large pipelines down into bite size, easier managed, chunks. Running them is as simple as:

vector -c ./configs/first.toml -c ./configs/second.toml -c ./more/*.toml

Lots of New Sinks

We all love a good sink. Now you can enjoy our latest offerings: gcp_stackdriver_logging, gcp_cloud_storage, logdna, humio_logs, loki and influxdb_metrics.
