> Related: is there a reason that DataFrame is a trait with a single impl? I'm wondering if it could be a concrete struct with the actual execution logic handling more exotic setups (custom TableProvider impls etc), which would free it from all the trait-imposed restrictions. Are we expecting to support multiple DF implementations? @jorgecarleitao might know the answer to that as he introduced the `DataFrame` trait initially. @ritchie46 has a dataframe library polars which maybe someday could be integrated: https://www.ritchievink.com/blog/2021/02/28/i-wrote-one-of-the-fastest-dataframe-libraries/. It is interesting to me that many of the polars features and implementation seems very similar to the features in `DataFusion` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
