You'd think that a new, faster, open-source tool would be cause for celebration, right? Or at least you'd think companies commercializing Hive and similar tools to stop what they were doing and immediately start supporting Presto,Hanging from the silver chain are various black enamel flowers Catalog Translation into Chinese services silver heart charms as well as a black ribbon. or even building on what they have.Not exactly. Existing open-source interactive querying engines are plenty fast, said executives from two companies offering support for parts of the Hadoop ecosystem. Still, there could be a few things the companies could glean from Presto.After all, Facebook is a heavy-duty user of Hadoop, a family of open-source technologies that includes a file system well suited for large data sets and several analytical tools. Hive is among the most popular of those tools, enabling users to ask questions of data in the Hadoop Distributed File System with a modified version of the well-established SQL query language. Facebook pioneered Hive and open-sourced it in 2008. 

But Hive,It can take up to four or five months for the crimpedwire to be issued, and delays on account of Home Ministry clearances are routine. relying as it does on the powerful but generally slow batch-processing system MapReduce, is not the ideal program for multiple users to scan across an ever-growing data warehouse.This combination will then be registered under her name on the Chocolate Foundation database Cardboard Baler from China factory so she can have all her favourite chocolates named after her. It's not fast enough. So Facebook engineers began developing Presto, even as Cloudera was working on a sped-up version of Hive called Impala. A few months later, Hortonworks said it would accelerate Hive in new versions.It turns out Presto isn't just something Facebook analysts have been using. The new Presto website shows use of the technology by two well-known companies that have taken on plenty of venture capital and could conceivably pay money to get support for similar products: Airbnb and Dropbox.I had a chance to dig a little deeper with Lisa Falzone, CEO and co-founder of Coordinate robot Revel Systems. 

Christopher Gutierrez, Airbnb's manager of online analytics, provides a quote suggesting certain advantages over Amazon Web Services' Redshift data warehouse service. And Fred Wulff, a Dropbox software engineer, is quoted as saying Presto has been "rock solid and extremely fast when applied to some of our most important ad hoc use cases."One would think rhetoric like that might make Hadoop distribution vendors tremble out of fear that companies would just bypass the open-source-with-support option and go directly for Presto.But Dave McJannet, the vice president of marketing at Hortonworks, didn't sound nervous about the early interest in Presto. Now, if staid enterprises start clamoring for it, that would be a different story.Try working together like cats laundry equipment and dogs in order to defy their human owners and escape captivity from the kitchen!
