QuestDB
QuestDB 是开源的时序数据库，主打写入吞吐与查询延迟：列式存储加时间分区，提供兼容 Postgres 的通信协议与一套面向时序的 SQL 扩展，常见写法是在查询里直接做时间采样和插值。带分层存储，老数据可以沉到更便宜的对象存储，适合指标、日志、行情这类按时间堆起来的数据。 🔗 文档: https://questdb.io/docs/ | GitHub Stars: 17k+
QuestDB is an open-source time-series database built around ingest throughput and query latency: columnar storage with time partitioning, a Postgres-compatible wire protocol and time-series SQL extensions that do sampling and interpolation inline. Tiered storage pushes older data to cheaper object storage, which fits metrics, logs and market ticks that pile up by timestamp. 🔗 Docs: https://questdb.io/docs/ | GitHub Stars: 17k+
