Parquet

Parquet is a columnar storage file format designed for efficiency with big data processing frameworks like Apache Hadoop and Spark.

Technical Details

Parquet organizes data by columns rather than rows, which enables better compression and more efficient queries for analytical workloads. It supports nested data structures and is optimized for handling complex data.

Advantages

  • Highly efficient columnar storage and compression
  • Excellent query performance for analytical workloads
  • Support for nested data structures
  • Schema evolution capabilities

Limitations

  • Not human-readable like CSV or JSON
  • Less suitable for row-oriented operations
  • Requires specialized tools for viewing and editing
  • More complex than simpler formats
NDJSON

NDJSON (Newline Delimited JSON) is a format where each line is a valid JSON object, making it easier to process large datasets sequentially.

Technical Details

Each line in an NDJSON file is a complete, self-contained JSON object ended by a newline character. This allows for streaming processing without loading the entire file into memory.

Advantages

  • Streaming-friendly for large datasets
  • Easy to append new records
  • Each record can be processed independently
  • Simpler to parse than JSON arrays for large datasets

Limitations

  • No support for cross-record references
  • Less widely supported than standard JSON
  • Each line must be a complete JSON object
  • Not suitable for deeply nested relationships

Common Use Cases
