Interactive Shuffle Sharding Explorer

A visual tool to understand workload isolation and blast radius reduction.

1. Simulate Shard Failures

Click on a shard to toggle its status between healthy (blue) and failed (red). Observe the impact on the routes below.

2. Observe Route Status

Click on a route to see its assigned shards and whether that assignment is shared with any other routes.

Healthy
Partially Impacted
Completely Down

3. Analyze the Impact
