Memories of the machine…

Interesting article on Computing today about in-memory databases and what is hampering adoption. The fact that, being in memory, persistence and recoverability is an issue, appears to be hampering mainstream adoption outside of data-warehousing and BI, etc – which is understandable. Availability is pretty damned important and there is no point in going as fast as you can if you might lose everything or have to undertake a lengthy rebuild.
It seems to me though that organisations should be starting to work on this sort of architecture – if only to prepare themselves for the next generation of infrastructure where persistent memory will (hopefully; everything crossed!) solve the availability issue. Have a read about HP’s ‘The Machine’ project which will give you an idea of where this stuff may be going….
