Concurrency is not just the ability to run long running queries with short/tactical ones. That is what they are talking about when they say concurrency. Another aspect of concurrency is the ability to support data modifications/loads while users are active on the system - AND NETEZZA SUCKS AT THIS. You run one or two large load jobs while many users are on the system and the whole thing goes to hell in a hand basket. So a lot of this is just marketing crap..

It somewhat improved in next releases. However I do not buy that "Netezza sees concurrency as a significant competitive advantage". I am not sure about the latest version, but the version we run in house, I do not see a good product like priority schedular of Oracle resource manager to let the short queries to pass through quickly. I may be wrong, but comments are welcome. Mitra Netezza in their first version had horrible concurrency issues. It somewhat improved in next releases.
