I'm finding myself with a couple of really big databases and my PC is throwing memory errors so I'm moving the project to polars and learning on the way in, and would like to read your experience in how you did it, what frustrate you and what you found good (I'm still getting used with the syntax, but I'm loving how fast it reads the databases)

There's this categorical column of integers that have some excepcional cases where some letters are included. I need to process the column except the excepcional cases to format the column, but I just found put that it was giving me a problem because pandas imported it as mixed type while polars just imported it as string respecting the original correct formatting.
