About QuestDB
English 简体中文 QuestDB is the open source, low latency time series database on open formats. It ingests millions of events per second, computes on live data in milliseconds, and keeps years of history queryable. One SQL engine spans ingestion, stream processing, and tiered storage. The engine is zero GC Java with C++ and Rust on the hot paths. Data lives in memory mapped, time partitioned columns. Queries run across all cores with SIMD and JIT compiled filters. There are no third party dependencies on the data path. Storage is tiered: a parallel write ahead log, native columnar partitions, and Apache Parquet. In…
