# DFHist

Utilities for histories and caches of pandas dataframes

J. M. F. Tsang (j.m.f.tsang@cantab.net)

## What is this?

DFHist lets you cache the results of functions that produce pandas dataframes, as well as maintaining a history of the dataframes on disk (as CSV files).

This is useful for running functions that produce large dataframes that can change over time, such as running SQL queries using pd.read_sql_query or querying an API.
