This document describes the step-by-step process for upgrading an existing Kafka 2.x cluster to Kafka 3.x using a sidecar (rolling) upgrade approach — where some brokers temporarily run Kafka 2 while others run Kafka 3. This ensures no cluster downtime and enables a…
To perform a rolling upgrade from Kafka 2.8.2.3.3.6.x-x to Kafka 3.7.2.3.4.3.x-x, follow these steps: Update server.properties on All Brokers. Rolling Upgrade from Kafka 2 to Kafka 3 To perform a rolling upgrade from Kafka 2.8.2.3.3.6.x-x to Kafka 3.7.2.3.4.3.x-x, follow these steps:…
The following example is based on Kafka 3 runtime arguments and may differ for Kafka 2. Since you already have Kafka, Pinot, and Zookeeper installed, ensure they are running. It is recommended to create new topics for each service to do testing.
This topic provides steps to start a standalone Kafka cluster in ZooKeeper mode, validate its functionality, and perform a rolling upgrade from Kafka 2.8.2.3.3.6.x-x to Kafka 3.7.2.3.4.3.x-x. For details about the ODP Standalone Binaries, see Accessing Acceldata Repositories. Once all…
This document outlines the steps to perform an in-place upgrade of the Kafka cluster from Kafka 2.x to Kafka 3.x using the same data directories and ZooKeeper quorum. Before starting the upgrade, verify that the Kafka 2 cluster is fully functional.
This page shows how to configure Pinot schema and table files for ingesting data from a Kerberized Kafka source. It includes Kafka security settings, JAAS config, and the command to add the table using pinot-admin.sh. Use the following command…

This page outlines the steps to perform an in-place upgrade of a Kafka cluster from Kafka 3.x to Kafka 4.x, using the same data directories. Before you start the upgrade, verify that the Kafka 3 cluster is fully functional. Verification: Messages…
helps you run Kafka clusters at scale. It automates Kafka operations such as monitoring cluster workload, rebalancing a cluster based on predefined constraints, and detecting and fixing anomalies. Cruise Control comprises four components — Load Monitor, Analyzer, Anomaly Detector, and Executor…
This page explains how to deploy a standalone Kafka 4 cluster in KRaft mode: get the Kafka binaries, configure the controller and broker, initialize storage, start the cluster, and create, write, and read events from a topic. Download the standalone binaries…
