Neither Greenplum nor eBay will say for the record that eBay is a Greenplum customer. Indeed, saying that is quite verboten. On the other hand, Greenplum’s press release boilerplate says that Skype is a Greenplum customer, and Skype is of course a subsidiary of eBay. (Edit: Speaking of silliness, fixed a typo there.)
The point of such distinctions is sometimes lost on me.
In related news, of Greenplum’s two customers who back in August were supposedly heading into production soon with petabyte-plus databases, one hasn’t yet made it to that size. (“As we speak” turned out to be a longer conversation than I might have anticipated ….) The other (of course unnamed) customer has, Greenplum assures me, made it that high. But upon checking with that (unnamed, in case I forgot to mention the point) customer, I don’t detect a whole lot of enthusiasm about Greenplum.
