ClickHouse

★ 40k

Column-oriented OLAP database that chews through billions of rows in milliseconds on modest hardware.

ClickHouse does the job of Snowflake, self-hosted. It is Apache-2.0-licensed, so you can do essentially what you like with it, and running it properly takes real ops work. Snowflake bills $100+ for it. 40k stars on GitHub.
