Prajwal Kadam developed an ONTAP S3-compatible storage backend for the TraceMachina/nativelink repository, focusing on optimizing performance for S3-backed operations. He implemented an integrated existence cache, which reduces latency by caching object existence checks, thereby streamlining frequent storage queries. Working primarily in Rust, Prajwal applied backend development and caching strategies to enhance both reliability and throughput of the S3-compatible store. His work addressed system integration challenges and included targeted fixes and improvements to the storage layer. The project leveraged Rust and the S3 API, demonstrating depth in cloud storage and performance optimization within a complex, production-oriented backend environment.
