Streaming JSON in Rust – Efficient parsing and transformation with minimal memory

Summary: Streaming JSON in Rust provides libraries for parsing and transforming large JSON files using a sliding window approach that avoids loading entire documents into memory. It includes tools for streaming parsing, key-based action triggers, JSON rewriting, and fast DynamoDB format conversion, offering improved performance and cleaner APIs.

What it does

It parses and transforms JSON streams using a sliding window, enabling processing of terabyte-scale files with kilobytes of memory. The libraries support streaming parsing, conditional actions during parsing, JSON rewriting, and efficient DynamoDB JSON conversion.

Who it's for

Developers handling large JSON datasets or requiring high-performance streaming transformations with minimal memory overhead.

Why it matters

It addresses complexity and inefficiency in streaming JSON processing by combining speed, low memory use, and maintainable code for large-scale JSON workflows.
