Release 60: kPow, LDAP, JAAS, and Compute

This is a big release, even by our standards.



Release #60 is available on Dockerhub and to download as a JAR file.

docker pull operatr/kpow:60
https://releases.operatr.io/operatr-2020-11-17-22-02.jar?AWSAccessKeyId=AKIAXNNKGCAKDUQSTKG4&Expires=1621163189&Signature=AwqBvAPkspN0FHXHdSmuZjti%2BTY%3D



Operatr is now kPow!

We recently announced the arrival of two new products:

  • kJQ: Streaming JQ for Apache Kafka will always be a part of kPow, but is also in beta as a standalone product.
  • kSynth: Declarative generated events and synthetic state machines for Apache Kafka. Currently in alpha and used internally at Operatr.IO HQ.


Now seems the time to drop the (frankly unfortunate) previous name and re-launch our flagship engineering toolkit for Apache Kafka as kPow.

In practical terms for you this means very little, though in time our artefacts will be released to operatr/kpow in Dockerhub rather than operatr/operatr.

To coincide with the arrival of new products and rebranding we have three new online resources:

  • operatr.io for information about Operatr.IO as a company and all of our products
  • kpow.io for information about kPow, including release notes and artefacts
  • docs.kpow.io for the new, Gitbook powered kPow User Guide!

Release 60 Improvements and Bugfixes


Thanks to your phenomenal bug reporting and feedback, kPow v60 is packed with improvements, including:

  • Maintaining UI state throughout a SAML session refresh
  • kPow restricts UI access to Authorized Roles when RBAC is configured
  • RBAC configuration now supports a list of roles per policy
  • Connect UI improvements to Task State and Group Lag sort order
  • System startup UI improvements
  • Configurable Data Policies Exclusions

LDAP, File, and JDBC Authentication via Jetty JAAS


Release 60 brings support for a variety of new User Authentication options, including LDAP, File, or JDBC, and all documented in our new User Guide!



kPow v60 also provides an enhanced UI with new Profile and Access Control pages.



Visualize and Control Consumption and Compute

The most exciting feature of kPow v60 is our new Compute Console.

kPow now offers the ability to visualize and monitor Consumer Group topologies in real-time (when coupled with Live Mode).

More than monitoring – the Compute Console allows you to reset consumer group offsets at a group, host, member, topic, or assignment level. kPow will schedule the reset and effect the action once you stop your consumer group. Scheduled mutations expire after 15 minutes and can be cancelled at any time.

We will soon extend the Compute Console to cover Kafka Streams topologies as well.

As this is a feature preview we would love your feedback, get us on Slack!
