Server Regression Fix

We use the common Java HTTP framework Jetty to serve the Kpow UI.

In release 64 we advanced our Jetty dependency from 9.4.30 to 9.4.36. We believe this caused a slow memory leak due to a change in Jetty behaviour regarding websocket buffering and that change not being supported by the websocket library we use.

This change reverts Jetty to 9.4.30.

Resolves an issue that occasionally impacted compute/group views.

Discover the kREPL, an interactive development environment for Apache Kafka that provides all the tooling required to consume Kafka topics and explore structured data with Klang - a language that blends JQ and Clojure.

This release brings all dependencies to current, ameliorating CVEs raised by our automated vulnerability scanning.

Message Header kJQ

Kpow introduces the ability to apply kJQ queries to message headers, allowing you to search tens of thousands of messages a second and match by header.

Kpow supports simple String header keys and values, representing your message headers as a JSON map of String to [String] (as keys can be repeated).

Normal kJQ query rules apply, if you require extended support for custom header serdes please contact support@factorhouse.io.

UI Improvements

Kpow now provides immediate feedback on all user actions, this release also polishes the tabular UI and context menu actions.

This small bugfix release corrects a label off-by-one error with horizontally displayed topologies.
