Happy to see activity around Polars. This has been my go-to library for data processing due to the enhanced ergonomics compared to Pandas and SQL.
But they were a bit quiet lately, and I started looking more and more into DuckDB recently… until the recent acquisition of DuckLab by AWS
I've been using clickhouse-local for quite some time, instead of DuckDB. There is also chDB.
After using pandas for 10 years, I favor SQL now, for some reason.
