How to Reset Kafka Consumer Group Offset

Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups command.

  1. List the topics to which the group is subscribed
kafka-consumer-groups --bootstrap-server <kafkahost:port> --group <group_id> --describe

Note the values under "CURRENT-OFFSET" and "LOG-END-OFFSET". "CURRENT-OFFSET" is the offset where this consumer group is currently at in each of the partitions.

  1. Reset the consumer offset for a topic (preview)

Last active July 6, 2023 19:53
A simple Ops helper script for Apache Kafka to generate a partition reassignment JSON snippet for moving partition leadership away from a given Kafka broker. Use cases include 1) safely restarting a broker while minimizing risk of data loss, 2) replacing a broker, 3) preparing a broker for maintenance.
#!/usr/bin/env bash
#
# File: kafka-move-leadership.sh
#
# Description
# ===========
#
# Generates a Kafka partition reassignment JSON snippet to STDOUT to move the leadership
# of any replicas away from the provided "source" broker to different, randomly selected
# "target" brokers. Run this script with `-h` to show detailed usage instructions.

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).
