SKILL.md
Kafka Mastery (Senior → Principal)
Operate
- Confirm whether Kafka is solving event streaming, integration decoupling, replayability, or auditability.
- Design topics, keys, and retention with business semantics and recovery strategy in mind.
- Treat consumer lag, rebalance behavior, and schema evolution as first-class concerns.
- Prefer explicit delivery semantics over magical “exactly once” assumptions.
Default Standards
- Partition by stable business keys with clear ordering needs.
- Consumers must be idempotent.
- Retention and compaction are product decisions, not only infra settings.
- Observe lag, throughput, error rate, rebalance churn, and ISR health.
