Convert NDJSON to PostgreSQL

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

PostgreSQL, often called Postgres, is a powerful, open-source object-relational database system.

It's known for being robust, extensible, and compliant with standards. PostgreSQL offers advanced features like complex queries, foreign keys, triggers, and transactional integrity.
