What is a PARQUET file?
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.
More Information
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 it for data-intensive applications that need to process and analyze large amounts of information. Parquet files work with Hadoop and other data-processing systems, including Apache Spark, Apache Hive, and other tools that support the Parquet format.
PARQUET files begin with the magic number PAR1 and contain one or more row groups that organize the file's data. The files also include metadata in a footer that describes the data stored in the files, including information about their columns and row groups. The PAR1 magic number also appears at the end of a PARQUET file, allowing applications to identify the file.
How to open a PARQUET file
You can use Parquet-tools (multiplatform), which is available as both a standalone tool and part of Apache Hadoop, to read and manipulate PARQUET files. DBConvert Parquet Viewer can also open PARQUET files, allowing you to read them locally in your web browser.
