Polars: Rust DataFrames Based on Apache Arrow

• ritchie46 6y ago
  As a hobby project I tried to build a DataFrame library in Rust. I got excited about the Apache Arrow project and wondered if this would succeed. After two months of development it is faster than pandas for groupby's and left and inner joins. I still got some ideas for the join algorithms. Eventually I'd also want to add a query planner for lazy evaluation.
