Kafka Consumer Group Design

Category: Engineering  ·  Sub-category: data-engineering  ·  Last updated:
Design Kafka consumer groups that survive rebalances, hit the right delivery guarantee (at-most/at-least/exactly-once), and handle poison messages without stalling the topic. Use when picking a partition assignment strategy (Range vs Sticky vs Cooperative-Sticky vs the new KIP-848 protocol), tuning heartbeat / session / max.poll.interval timeouts, choosing manual vs auto offset commits, designing dead-letter or retry topics, or migrating from Classic to the next-gen Consumer protocol. NOT for Kafka cluster ops (broker tuning, partition reassignment), schema design (Avro/Protobuf/Schema Registry), or stream processing topology (use a kafka-streams skill).

From the source SKILL.md

A Kafka consumer group is a coordination protocol, not a load balancer. Picking the wrong assignment strategy or heartbeat tuning produces "rebalance storms" that pause the entire group for tens of seconds. Picking the wrong commit pattern produces silent data loss or silent duplicates. This skill encodes the protocol-level rules and the version-specific gotchas — including the 2024-GA KIP-848 next-gen rebalance protocol that replaces the global synchronization barrier.

What this skill does

Kafka Consumer Group Design is a community-contributed Claude Code skill in the data-engineering sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/kafka-consumer-group-design/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when picking a partition assignment strategy (Range vs Sticky vs Cooperative-Sticky vs the new KIP-848 protocol), tuning heartbeat / session / max.poll.

Who uses this skill

The Kafka Consumer Group Design Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Kafka Consumer Group Design" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the Kafka Consumer Group Design skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools).
