This week, Teradata introduced its in-memory capabilities. The press release is here.
In-memory is the current fastest commercial medium for data storage, upwards of thousands of times faster than HDD. Naturally, it is expensive relatively speaking or it would be more pervasive now. However, the price point has lowered recently and we are having an in-memory hardware renaissance. As Tony Baer of Ovum said in a tweet response to me: "w/DRAM cheap,takes SmartCaching to nextlevel."
Teradata takes in-memory a step further by considering the relative priority of data and, though all data is backed by disk, it will automatically transfer it in and out of memory as appropriate, in a feature it calls Intelligent Memory. This is the data "80/20 rule" at work. After 7 days of usage, Teradata says the allocation will be fairly settled. Teradata has found that, across multiple environments, 85% of I/O uses 10% of the cylinders. It's in-memory driven by data temperature (and this extends to HDD and SSD).
You still need to allocate the memory (and SSD) initially but whatever you allocate will be intelligently utilized. It will run will run across the Teradata family: the 670, 1650, 2700 and 6700 models.
It behooves us to seek out the fastest medium for data that can be utilized effectively in the organization and delivers maximum ROI. Those who understand the possibilities for data today should be sharing and stimulating the possibilities for information in the organization. All productive efforts at information management go to the bottom line.
