Convert Arrow to NDJSON

Apache Arrow is a cross-language development platform for in-memory data that specifies a standardized language-independent columnar memory format for flat and hierarchical data, organized for efficient analytic operations on modern hardware like CPUs and GPUs.

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

Key Features

• Columnar memory format for flat and hierarchical data
• Language-agnostic specification
• Optimized for analytical processing and modern hardware
• Support for complex nested data structures
• Efficient zero-copy reads

Use Cases

Apache Arrow is particularly useful in scenarios involving:

• Big data processing and analytics
• Machine learning and AI pipelines
• Data interchange between different systems and languages
• High-performance computing applications

Its efficient memory layout and standardized format make it an excellent choice for applications requiring fast data processing and interoperability between different tools and languages.

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.
