An Viewer and Operator for Kafka.

---

Description

Today, we have lots of Kafka tools to use, but we have barely neat web Kafka UI to use and bind to our business services. Hence, KaViewer is here, which is made for both Local, On-Premise and Cloud Native service. KaViewer web ui, let you can view and operate kafka with permission control, more details see Architecture.

Feature

Functions

• Add/Delete New Kafka Cluster/Broker (Not delete the real instance). ✅
• Add/Delete Topic. ✅
• Publish/Consumer Messages. ✅

Permission Control

Based on those functions,KaViewer provide two common mode to suit the two different scenario.

• FULL mode, support all the operations above.
• LITE mode (default), only support to view kafka message.

And KaViewer support the custom toggles config to enable or disable those operations based on the two mode above as well.

Configurations

Group	Config Name	Config Value	Description
Cluster	kaviewer.toggle.cluster.create	Boolean	Allow to add new cluster (true/false)
Cluster	kaviewer.toggle.cluster.delete	Boolean	Allow to delete new cluster (true/false)
Topic	kaviewer.toggle.topic.create	Boolean	Allow to create new topic (true/false)
Topic	kaviewer.toggle.topic.delete	Boolean	Allow to delete new topic (true/false)
Consumer	kaviewer.toggle.consumer.write	Boolean	Allow to publish new message (true/false)
Consumer	kaviewer.toggle.consumer.read	Boolean	Allow to consume new message (true/false)

Persist API

By default, KaViewer won't persist the registered connections when it shut down.

KaViewer provides the exposed API interface Persistent , which you can do the enhancement to persist KaViewer data. It is similar to SpringBoot autoconfiguration mechanism. You can import kaviewer-runner.jar as dependency and implement the Persistent interface, then add the META-INF/kaviewer.factories to do the trick.

Usage

Require Java >=11 and Kafka >=0.11.0.
