Convert Parquet to JSONLines

Apache Parquet is a columnar storage format optimized for use with big data processing frameworks. It offers efficient data compression and encoding schemes, which leads to significant storage savings and improved read performance.

Parquet is designed to support complex nested data structures and enables efficient querying and manipulation of specific columns without reading the entire dataset.

Compression

Parquet supports various compression algorithms such as Snappy, Gzip, and LZO. These compression techniques help in reducing the storage space and improving the performance of data processing tasks.

JSON Lines, also known as JSONL, is a convenient format for storing structured data that may be processed one record at a time.

Each line in a JSON Lines file is a valid JSON object, typically representing a single record. The lines are separated by newline characters, making it easy to read and write sequentially.

This format is particularly useful for logging, streaming, and other scenarios where you want to process data line by line without having to parse an entire JSON array.
