Apache Avro is a row-oriented remote procedure call and data serialization framework developed within Apache's Hadoop project. It uses JSON for defining data types and protocols, and serializes data in a compact binary format.
Avro is designed to support complex nested data structures and enables efficient querying and manipulation of specific columns without reading the entire dataset.
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.
