Java parser Hardwood boosts Apache Parquet speed with AI

By PulseAugur Editorial · [1 sources] ·

Gunnar Morling, known for the 1 Billion Row Challenge, has released Hardwood, a new Java parser for Apache Parquet. This parser is designed to be zero-dependency and ultra-fast, utilizing page-level parallelization with Java Virtual Threads to optimize CPU core usage and concurrency. Morling highlights that the parser was built with AI assistance, which sped up development, but emphasizes that human oversight was crucial for maintaining code quality and preventing regressions.
