This moves to predominantly supporting only lazy dataframes for most operations. It removes a lot of the type conversion between lazy and eager dataframes based on what was inputted into the command. For the most part the changes will mean: * You will need to run `polars collect` after performing operations * The into-lazy command has been removed as it is redundant. * When opening files a lazy frame will be outputted by default if the reader supports lazy frames A list of individual command changes can be found [here](https://hackmd.io/@nucore/Bk-3V-hW0) --------- Co-authored-by: Ian Manske <ian.manske@pm.me>
