NDJSON (Newline Delimited JSON) is a convenient format for storing or streaming structured data that may be processed one record at a time. Each line in an NDJSON file is a valid JSON object, separated by a newline character.

This format is particularly useful for handling large datasets, as it allows for easy parsing and processing of data line by line without loading the entire file into memory.

Key Features

  • Each line is a self-contained JSON object
  • Simple to read and write sequentially
  • Ideal for streaming and logging applications
  • Supports partial processing of large datasets

NDJSON is commonly used in data pipelines, log processing, and scenarios where you need to append new data to existing files without modifying the entire structure.


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.
