Co je soubor PARQUET?
A PARQUET file is a data file saved in the Apache Parquet format. It stores tabular data in a column-oriented layout, grouping rows and storing values for each column together. This structure can make it more efficient for data-processing applications to retrieve only the columns they need.

Apache Parquet was originally developed as part of the Hadoop ecosystem and is now used by many data-processing and analytics applications. Apache Hadoop is an open-source software framework designed to store and process large datasets across multiple computers. People commonly use Parquet for data-intensive applications that need to process and analyze large amounts of information.
PARQUET files begin with the PAR1 magic number, a sequence of characters that applications use to identify the file as a Parquet file. They contain one or more row groups that organize the file's data and include metadata in a footer that describes the data, including information about its columns and row groups. The PAR1 magic number also appears at the end of a PARQUET file.
