re: Microsoft In-Memory Move Challenges SAP, Oracle
I think the proof of the technology is in customer implementations. HANA performance papers show simple star schema with a single large fact table. Once you go beyond that into real world implementations (multiple large fact tables and many to many relationships between dimensions) HANA performance remains unknown. Especially when resolving the query requires data movement between the nodes - and may result in eventual data spills on the disk.

Leyland is incorrect in suggesting that HANA "falls off a cliff" when the data size exceeds the memory available. HANA pages data to disk when memory becomes constrained.

When Hekaton arrives in 2015 MSFT will be five years and 3-4 release cycles behind HANA. It is only software so they might catch up... in 2018 or 2019.
