Show HN: Samchika – A Java Library for Fast, Multithreaded File Processing
12 by mprataps | 3 comments on Hacker News.
Hi HN,I built a Java library called SmartFileProcessor to make high-performance, multi-threaded file processing simpler and more maintainable. Most Java file processing solutions either involve a lot of boilerplate or don’t handle concurrency, backpressure, or metrics well out of the box. I needed something fast, clean, and production-friendly — so I built this. Key features: Multi-threaded line/batch processing using a configurable thread pool Producer/consumer model with built-in backpressure Buffered, asynchronous writing with optional auto-flush Live metrics: memory usage, throughput, thread times, queue stats Simple builder API — minimal setup to get going Output metrics to JSON, CSV, or human-readable format Use cases: Large CSV or log file parsing ETL pre-processing Line-by-line filtering and transformation Batch preparation before ingestion I’d really appreciate your feedback — feature ideas, performance improvements, critiques, or whether this solves a real problem for others. Thanks for checking it out!
