To my understanding parquet files have min/max statistics for columns.
my question is how to read those stats using python without reading the entire file?

If it helps, I also have `_common_metadata` and `_metadata` files.

---

my specific problem is getting the max date for each stock exchange partition in this file system (each year partition contains multiple parquet files that have date column) : 

```
C:.
│   _common_metadata
│   _metadata
├───source=NASDAQ
│   ├───year=2017
│   └───year=2018
├───source=London_Stock_Exchange
│   ├───year=2014
│   ├───year=2015
├───source=Japan_Exchange_Group
│   ├───year=2017
│   └───year=2018
└───source=Euronext
    ├───year=2017
    └───year=2018

```
