Hi Furcy, Many thanks for your email :)
My latest info was that the rename took place due to objections by Teradata, but didn't know if they had actually requested to take it off the distribution entirely. Does anybody else have an idea on the licensing aspect of this? What exactly has Teradata patented? Is it the technique to parse the rows in a such a manner? Any tips/techniques would be highly appreciated.
