SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill simulates a rolling-restart chaos drill for RobustMQ replicas, allowing users to verify ISR (In-Sync Replica) replication, leader failover, and recovery.

Core Features & Use Cases

  • ISR Replication Verification: Checks replica replication, leader failover, and recovery after rolling restarts.
  • Chaos Simulation: Simulates kill-one-node + write + restart + verify across a 3-replica shard.
  • Use Case: Ideal for users who want to ensure their 3-replica shard is functioning correctly and to verify the system's behavior under churn.

Quick Start

Run the isr-replication-drill skill to perform the chaos drill on your RobustMQ cluster.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I test ISR replication and leader failover in a RobustMQ cluster?▼

You can test ISR replication by running a rolling-restart chaos drill that kills one node, continues writes, restarts the node, and verifies replica recovery and leader failover.

What is a rolling-restart chaos drill for replica health checks?▼

A rolling-restart chaos drill simulates killing a single node, writing data during the outage, restarting the node, and verifying ISR replication and leader failover across a 3-replica shard.

Do I need a specific cluster size to verify RobustMQ disaster recovery?▼

Yes, verifying RobustMQ disaster recovery requires a running 3-node RobustMQ cluster along with specific configuration files to properly execute the rolling-restart chaos scenario.

Can I simulate a node failure and write traffic simultaneously for cluster testing?▼

Yes, this chaos simulation kills one node in a 3-replica shard, continues write traffic during the outage, restarts the node, and verifies ISR replication and recovery under churn.

Why does leader failover need to be tested under churn in a 3-replica shard?▼

Testing leader failover under churn verifies that ISR replication correctly maintains data consistency and system availability when a single node is killed and restarted within a RobustMQ cluster.
