Just in case you read about this little project that my friends and I have been working on for the past few months:
12.1 PB of raw data compressed to just 2 PB of RAM and disk in SAP HANA and SAP IQ.
Not one to rest, we are trying to push the limits even further with respect to the size of the database and data load speed. If you recall last year, we loaded 34 TB/hour into SAP IQ (http://global.sap.com/corporate-en/news.epx?PressID=21160).
So, stay tuned for a lot more exciting news on IQ pushing the limits of structured and unstructured data. Along with all of this will be a lot of write-ups on what was done, tested, the data, structure, etc.
