Query Kafka Messages with Know Streaming: A Step‑by‑Step Guide
This article explains how to use Know Streaming’s zero‑intrusion plugin to query Kafka messages, detailing the UI flow, multi‑dimensional filter options such as offset, partition, and key/value selection, the data truncation feature, and the underlying implementation that builds a KafkaConsumer and leverages KafkaAdminClient.
Feature Overview
Viewing Kafka messages is a frequently requested capability, but unlike RocketMQ it lacks built‑in complex query support.
