This Skill helps diagnose StarRocks tablet-level storage and balance problems that cause slow queries, write blocks, replica errors, excessive metadata overhead, and disk migration loops.
Ask for a tablet-health investigation of a StarRocks table and include any symptoms such as skew, too many versions, replica errors, or disk balance retries so the Skill can identify the likely cause and next remediation steps.

Diagnose StarRocks tablet health by inspecting tablet counts, version buildup, rowset pressure, and unhealthy replica states to isolate the failing storage layer causing slow queries. This process matches symptoms to root causes like compaction lag or bad replicas.
Data skew and replica distribution imbalance in StarRcks tablets stem from extreme data-size variance, over-sharding, and poor bucket key design. Detect these conditions by analyzing tablet distribution checks to identify uneven scan patterns and FE pressure.
Fix StarRocks compaction lag and excessive tablet versions by evaluating version and rowset thresholds against unhealthy replica states. Apply root-cause recovery guidance to resolve metadata overhead and clear version buildup blocking tablet operations.
StarRocks disk balance retry loops get stuck due to replica distribution imbalance and error-state replicas. Recover by tracing the disk migration failures, verifying replica repair actions, and confirming balanced tablet distribution across disks.
Redesign bucket keys to resolve StarRocks tablet skew when one tablet is far larger than others, creating uneven query scans. Confirm the skew pattern through tablet distribution checks and apply a safer bucket key redesign for balanced data.
