Open-source, low-latency time-series database with SQL, streaming ingestion, and tiered storage using native columns and Apache Parquet.
Why you might care
Suited to market data, telemetry, and real-time analytics where high ingest rates and fast SQL queries on recent data matter. Stores data in open formats (Parquet, Arrow, Iceberg) so other tools can read it, and can convert cold partitions to Parquet with ALTER TABLE. Benchmarks in the README are the project's own measurements.
