#2> Tenzing is currently used internally at Google by 1000+ employees and serves 10000+ queries per day
So that's 10 queries/employee/day. That screams "experimental". Still, this would be very nice.

that doesn't say how big these queries are
and this was quite a while ago

#4It would be interesting to know the identity of the vendor for "DBMS-X". I work in the "enterprise" data warehouse space and I'm trying to advocate moving away from "database appliances" towards distributed computing, and having a quotable source from Google would be very compelling.

#5Isn't this a Google version of Hive, which was open sourced by Facebook and provides an SQL style syntax to Hadoop. Queries aren't quick, it just allows offline data crunching to be coded quickly with out users having to code lots of map reduce. Cool concept but dont expect to see the online part of web apps powered by this.

Well this is pretty much a given isn't it? It's just a SQL implementation. It doesn't say anything about the underlying storage and guarantees. Given that it runs on GFS and Bigtable, unless these tech supports ACID, don't expect Tenzing to be able to support it either. Here's a quote from the paper:
Tenzing is not ACID compliant - specifically, we are atomic, consistent and
durable, but do not support isolation.Re: Tenzing: A SQL Implementation On The MapReduce Framework
#8How does this relate to Dremel? I thought Dremel had a SQL frontend to MapReduce that was already in wide use at Google.

I'm curious - what sorts of work do you do in the data warehousing space? Do you work as a consultant, or as an implementor at a customer of data warehouse products?
It seems to me that that whole industry (DW & ETL) is a dinosaur whose lunch is about to get eaten by some upstarts.
