You can add ClickHouse to the list.

While it is not a new database - it has been around since 2016, and in many areas it became almost ubiquitous, it is still less known to many potential users than it should be.

Many algorithms and ideas originated in ClickHouse and has found their usage in other systems like Apache Arrow, Datafusion, Iceberg, DuckDB, Velox, Apache Doris, Starrocks, TiDB, Tensorbase, YDB, Firebolt, Databend.
