This document discusses benchmarking TPC-H queries in MongoDB compared to MySQL. It introduces MongoDB and describes setting up the TPC-H data by embedding all tables into a single MongoDB collection. Six sample queries are presented and run using Map-Reduce and the Aggregation Framework. Benchmark results show MongoDB performing worse than MySQL on all queries due to data conversion difficulties and MongoDB's immature Aggregation Framework. The document concludes that while MongoDB is suitable for some applications, it is not well-suited to complex queries like those in TPC-H due to its lack of standard query language and server-side processing abilities.
