Facebook Presto

Potentially raising the bar on SQL scalability, Facebook has released open source SQL query engine called Presto that was built to work with petabyte-sized data warehouses.

Currently, more than 1,000 Facebook employees use Presto daily to run 30,000 interactive queries, involving over a petabyte of processing. The company has scaled the software to run on a 1000-node cluster

Unlike Hive, Presto does not use MapReduce, which involves writing results back to disk. Instead, Presto compiles parts of the query on the fly and does all of its processing in memory. As a result, Facebook claims Presto is 10 times better in terms of CPU efficiency and latency than the Hive and MapReduce combo.
Now, Facebook wants other data-driven organizations to use, and it hopes, refine Presto. The company has posted the software’s source code at The software is already being tested by a number of other large Internet services, namely AirBnB and Dropbox.

Big Data Expo is the single most effective event for you to learn how to use you own enterprise data – processed in the cloud – most effectively to drive value for your business.

A recent Gartner report predicts that the volume of enterprise data overall will increase by a phenomenal 650% over the next five years.

These two unstoppable enterprise IT trends, Cloud Computing and Big Data, will converge in Silicon Valley at Big Data Expo 2013 Silicon Valley – being held November 4 - 7, 2013, at the Santa Clara Convention Center in Santa Clara, CA.

It offers in Silicon Valley a vast selection of technical and strategic breakout sessions, General Sessions, Industry Keynotes, our signature discussion "Power Panels" and a bustling Expo floor complete with two busy Demo Theaters so that as a delegate you can kick the tires of solutions and offerings, and discuss one-on-one with all the leading Cloud and Big Data players what they are offering and how to make use of it in your particular situation.

Just as Big Data and Cloud solutions will be side by side on the Expo floor, so they are in the conference program. We're including below a sampler of the breakouts you can look forward to in the Big Data part of the overall technical program...and if you look at the welter of company logos at the very bottom you'll get a foretaste of the hundreds of companies in attendance on the Expo floor.
