What is a PARQUET file? A PARQUET file is a dataset saved in the Apache Parquet format. It contains column-based data split into row groups. Projects that use Apache Hadoop software utilities often process data saved in the PARQUET format.

More Information Apache Hadoop is an open-source software library used to process large data sets within a distributed computing system. Typically, projects created using Hadoop are used to solve complex problems that require analyzing incredibly large amounts of data. Any project that uses Hadoop can store column-based data in PARQUET files. Each PARQUET file contains a magic number, PAR1 , followed by row groups that specify the data each column contains. The files also contain various metadata stored in footer entries linked to each data chunk.
