Apache Hudi is an open-source data lake platform that brings ACID transactional guarantees to the data lake. Our teams have had a great experience using Hudi in a high-volume, high-throughput scenario with real-time inserts and upserts. We particularly like the flexibility Hudi offers for customizing the compaction algorithm which helps in dealing with "small files" problems. Apache Hudi falls in the same category as Delta Lake and Apache Iceberg. They all support similar features, but each differs in the underlying implementations and detailed feature lists.
