Facebook Presto - See my comment here: https://news.ycombinator.com/item?id=13626109

Facebook Presto, a MPP SQL Engine written in Java. https://github.com/prestodb/presto I have learned a lot from reading the source code and watching it develop. It is written in mo…

The author is missing a big gap between 5TB - 1PB. For most workloads, I would not look to Hadoop at the 5TB+ scale of data. I would first look at Impala or Redshift. http://blog.c…

Your links are looking at just google.com vs yahoo.com. The cnet article is referring to web properties owned by google vs properties owned by yahoo.

That explains why debaserab2 was able to find b.scorecardresearch for Yahoo, but not Google.
