polarstypes 0.1.2

This library is for utility functions around the polars dataframe library, paticulary compressing integer datatypes and also sting to categorical

polars-types

This library is centered around down casting datatypes in python polars. hopefully this kind of feature will be standard eventually The library can help polars users achieve the memory compression offered by the underlying data format used for python-polars - a columnar data store

There are so far two key functions

One function that identifies integer ranges and selects the appropriate integer datatype (bit resolution and signedness) One function that converts non-unique string columns to categorical columns

Future:

• itentify non-repeating values as attributes or as type literal
