Definitely clickhouse ecosystem.

- For querying csv data from command line, I use clickhouse-local.

- For querying csv data programmatically using a library, I use chdb (embedded version of clickhouse)

- For querying large amount of csv data programmatically, I offload it to clickhouse cluster which can do processing in distributed fashion.

If you are looking from query performance perspective, this blog is useful: https://www.vantage.sh/blog/clickhouse-local-vs-duckdb
