Why Parquet?

Parquet has been created to efficiently compress and store data big amounts of data.

Here is how to save a DataFrame in Parquet format.

# Import the Pandas library
import pandas as pd

# We create our example dataframe
df = pd.DataFrame({"col1" : range(0,10)})

# We save the dataframe as parquet
df.to_parquet('my_df.parquet.gzip', compression="gzip")

Here you are! You now know how to save a DataFrame in Parquet format!
