Description
Add a visual heatmap to the cluster view that shows slot-level CPU utilization across the cluster using CLUSTER SLOT-STATS. This helps operators quickly identify hot slots and unbalanced load distribution for resharding decisions.
Prior Art
The slot-level approach for identifying hot keys via CLUSTER SLOT-STATS was already implemented in PR #105. This issue extends that work into a visual heatmap representation that surfaces hot slots at a glance without requiring the user to start MONITOR.
Requirements
- Visual heatmap of slot ranges colored by CPU microseconds
- Requires
cluster-slot-stats-enabled to be set on the cluster
- Drill-down from hot slot to the keys within that slot
Target Release
1.3.0 (September)
