Use this skill whenever working with QuestDB — a high-performance time-series database. Trigger on any mention of QuestDB, time-series SQL with SAMPLE BY, LATEST ON, ASOF JOIN, ILP ingestion, or the questdb Python/Go/Java/Rust/.NET client libraries. Also trigger when writing Grafana queries against QuestDB, creating materialized views for time-series rollups, working with order book or financial market data in QuestDB, or any SQL that involves designated timestamps or time-partitioned tables. QuestDB extends SQL with unique time-series keywords — standard PostgreSQL or MySQL patterns will fail. Always read this skill before writing QuestDB SQL to avoid hallucinating incorrect syntax.

Create, review, and improve QuestDB documentation pages. Covers SQL reference, guides, cookbook recipes, syntax blocks, examples, page structure, and quality checks. Use when writing new docs, reviewing existing pages, adding examples, or restructuring content in the questdb/documentation repo (used both standalone and as a submodule of questdb.io).

Run full TSBS (Time Series Benchmark Suite) benchmarks against QuestDB in Docker, including prerequisite checks, TSBS build, data generation, loading, query generation, and benchmark execution. Use when asked to set up or run QuestDB TSBS performance tests end-to-end.
