Leverage PyArrow for Efficient Parquet Data Filtering

Leverage PyArrow for Efficient Parquet Data Filtering

When dealing with Parquet files in pandas, it is common to first load the data into a pandas DataFrame and then apply filters.

To improve query execution speed, push down the filers to the PyArrow engine to leverage PyArrow’s processing optimizations.

In the code above, filtering a dataset of 100 million rows using PyArrow is approximately 113 times faster than filtering using pandas.
