frameit

Frameit is a DataFrame caching tool that is designed to work on pandas and polars data objects. The tool is intended to be simple and make the process of running expensive functions that are called several times in a program less painful.

Examples

import pandas as pd

from frameit import frameit

@frameit
def some_expensive_function():
    df = pd.DataFrame()
    ...
    return df

import polars as pl

from frameit import frameit

@frameit(max_size=5e6, max_time=20)
def some_expensive_function():
    df1 = pl.DataFrame()
    df2 = pl.DataFrame()
    df3 = pl.DataFrame()
    ...
    return df1, df2, df3

import pandas as pd

from frameit import frameit, clear_cache

        # Some code that calls a set of expensive functions
        # that produce some dataframes that are relatively
        # static
        ...

    # End of the program
    clear_cache()
