Kevin Closson doesn’t like MPP
Kevin Closson of Oracle offers a long criticism of the popularity of MPP. Key takeaways include:
- TPC-H benchmarks that show Oracle as somewhat superior to DB2 are highly significant.
- TPC-H benchmarks in which MPP vendors destroy Oracle are too unimportant to even mention.
- SMP did better than MPP the last time he was in a position to judge (which evidently was some time during the Clinton Administration), so it surely must still be superior for all purposes today.

The Explosion in DBMS Choice
If there’s one central theme to DBMS2, it’s that modern DBMS alternatives should in many cases be used instead of the traditional market leaders. So it was only a matter of time before somebody sponsored a white paper on that subject. The paper, sponsored by EnterpriseDB, is now posted along with my other recent white papers. Its conclusion — summarizing what kinds of database management system you should use in which circumstances — is reproduced below.
Many new applications are built on existing databases, adding new features to already-operating systems. But others are built in connection with truly new databases. And in the latter cases, it’s rare that a market-leading product is the best choice. Mid-range DBMS (for OLTP) or specialty data warehousing systems (for analytics) are usually just as capable, and much more cost-effective. Exceptions arise mainly in three kinds of cases:
- Small enterprises with very limited staff.
- Large enterprises that have negotiated heavily-discounted deals for a market-leading product.
- Super-high-end OLTP apps that need absolute top throughput (or security certifications, etc.)
Otherwise, the less costly products are typically the wiser choice. Read more
