What problem does it solve?
This Skill helps you administer StarRocks tablet placement so disk usage and tablet counts stay balanced across Backend (BE) nodes and disk paths, while avoiding unsafe operations during scaling and failure scenarios.
Core Features & Use Cases
- Diagnose storage skew by inspecting per-BE disk utilization (including max per-disk path usage) and quantifying imbalance thresholds.
- Administer rebalancing operations for adding new BEs, decommissioning BEs, and recovering from BE failures while monitoring repair vs balance workloads.
- Tune balance behavior using dynamic FE parameters (e.g., balance_load_score_threshold, tablet scheduler strategy, concurrency/throttles) to control migration aggressiveness.
- Monitor and forecast migration progress using
SHOW PROC '/cluster_balance'and estimate days-to-full based on current and recent growth signals.
Quick Start
Ask the agent to help you add a new BE and then verify rebalancing completion by checking SHOW BACKENDS and SHOW PROC '/cluster_balance/overview'.
