GreptimeDB Performance Tuning

Apply server config and table-option changes to improve GreptimeDB performance. This skill covers the live-tunable / deployment-level knobs. Schema-level decisions (primary key, indexes, append-only, partitioning) live in greptimedb-table-design. If you don't yet know what to tune, run greptimedb-performance-diagnosis first to find the bottleneck.

The workflow

Phase 1. Identify the goal and version

Confirm what to optimize for (query latency, write throughput, or memory/disk footprint) and ask for the GreptimeDB version — defaults and available options differ across versions.
