@yohplala, I thought you would find this idea and implementation interesting (I am not asking for you to do anything, just for your curiosity) |

@rjzamora , this is a really useful new feature! I could use just a little help integrating with dask - the two failing tests could be changed to be simpler and pass with and without this change, but I wouldn't mind your thoughts. Secondly, doing this also revealed that row-filtering, which fastparquet supports at the ParquetFile API level (in .to_pandas() ), cannot be called by dask, which calls fastparquet.core functions directly. I'm not sure what to do about that, short of duplicating the relevant code. |
