Tenzir Node v4.20

Tenzir Node v4.20 is here, bringing a host of under-the-hood improvements that pave the way for exciting upcoming changes to the Tenzir Platform.

Under-the-hood Improvements

In this release, we've focused on improvements that will enable upcoming features of the Tenzir Platform.

Package Management

We've enhanced package management in the node, enabling seamless package upgrades on app.tenzir.com without the need to uninstall them first. This improvement sets the stage for smoother and more efficient updates in the future.

Slack Integration

Introducing the new Send to Slack package! Now, sending a message to a Slack channel from a Tenzir Node is as simple as publishing events on the slack topic:

// tql2
from {
  message: "Hello, world!"
}
publish "slack"

Caching

We're also happy to unveil the experimental cache operator. This operator creates an in-memory cache of events, allowing subsequent uses of the same cache to skip running the pipeline leading up to it. This enhancement promises to drive significant improvements to the Explorer and Dashboards, making data exploration more interactive and efficient.

Stabilizing the metrics Operator

Since the introduction of the metrics operator in Tenzir Node v4.8, our goal has been to replace the old metrics subsystem with a new, pipeline-first approach that enhances our dashboards. With the release of metrics rebuild, we've successfully ported all metrics to the new system. The old metrics subsystem configured under tenzir.metrics in the configuration file is now obsolete.

Migrating to the metrics operator

If you're still using the old metrics subsystem, be sure to check out our guide on collecting metrics and the metrics operator reference, which includes a comprehensive list of available metrics and their values.

Progress on TQL2

We've made significant strides in enhancing TQL2 over the past month. New features include string classification and transformation (<string>.to_upper(), <string>.is_lower()), computing CommunityID flow hashes, indexing into lists, and accessing secrets and environment variables (secret(<string>), env(<string>)), among others.

We're currently in the process of porting all remaining functionality from TQL1 to TQL2 and will soon introduce a comprehensive reference for TQL2's operators and functions.

Other Changes

This release also includes numerous small bug fixes and additional under-the-hood improvements. For a detailed list of changes, be sure to check out the changelog.
