Twitter’s service is nothing if not fast-moving, and on Tuesday night the company published a blog post detailing the database that helps it keep up. Called Manhattan, it’s a distributed, real-time database built to serve multiple teams and applications within the company. It’s also something of an indictment against existing open source database technologies, at least when it comes to handling th
Qubole, the cloud-based Hadoop service launched by Hive creators Ashish Thusoo and Joydeep Sen Sarma in 2012, is now offering users access to Presto, Facebook’s system interactive SQL queries on data stored in Hadoop. Facebook first announced it had created Presto in June, and then open sourced the technology in November. The type of capability Presto provides — fast, interactive SQL queries on Ha
At a conference for developers at Facebook (s fb) headquarters on Thursday, engineers working for the social networking giant revealed that it’s using a new homemade query engine called Presto to do fast interactive analysis on its already enormous 250-petabyte-and-growing data warehouse. More than 850 Facebook employees use Presto every day, scanning 320 TB each day, engineer Martin Traverso said
Amazon(s amzn) Web Services is the default, go-to IT infrastructure of choice for startups, right? Right. Er, well not always. No one disputes that AWS provides an impressive and ever-growing array of compute, storage and networking resources. Update: it just launched AWS Activate, a program to help startups build and run scalable AWS implementations, for example. Most nascent startups would be nu
Google (s goog) silently did something revolutionary on Thursday. It open sourced a tool called word2vec, prepackaged deep-learning software designed to understand the relationships between words with no human guidance. Just input a textual data set and let underlying predictive models get to work learning. “This is a really, really, really big deal,” said Jeremy Howard, president and chief scient
Q: What do you get when you mix Facebook’s (s fb) extensive memcached usage with its strategy of “cold storage” for infrequently accessed data? A: McDipper, a Facebook-built implementation of the popular memcached key-value store designed to run on flash memory rather than pricier DRAM. Memcached, for the unfamiliar, is an open-source key-value store that caches frequently accessed data in memory
Here’s something to ponder for those who don’t see Google(s goog) Compute Engine as ready for primetime: RightScale will start reselling and providing first-line support of the Google public cloud infrastructure. This is big news. RightScale prides itself on providing cross-cloud monitoring, alerts and management — for Amazon(S amzn) Web Services, for Rackspace(s rax), for HP(s hpq) Cloud and now
The advent of big data hasn’t changed the ideas behind most enterprise security practices, but it has made them better. While network security and endpoint security have always relied on the processing of files or traffic against threat databases of to determine whether they’re dangerous, big data lets them gather, store and analyze much more data. The result, in theory, are products that are more
Over the past year, I’ve seen a lot of startups, projects and tools that aim to bring fairly advanced analytic capabilities to programmers. Sometimes they do this by enabling simple scripts that result in powerful dashboards or processes, while other times they just deliver the data in an easy-to-consume manner with little work at all on the developer’s part. I think this is a meaningful trend. In
Here’s the thing about being an Amazon(s amzn) Web Services software partner: you’re going to be competing with Amazon Web Services. Case in point: On Wednesday at the AWS: Reinvent show, Amazon announced the preview of its Redshift data warehousing service to considerable hubbub — pitching it as a much-less costly competitor to Oracle(s orcl), IBM(s ibm), Hewlett-Packard(s hpq) and Teradata(s tdc
AppFog Founder and CEO Lucas Carlson isn’t shy about touting platform-as-a-service as the ideal way for developers to access cloud computing resources, but he isn’t blind either. Although PaaS has been around for a couple years now and has already spurred hundreds of millions in M&A spending, Carlson knows it’s nowhere near the mainstream yet. Carlson lays out his version of the evolution of cloud
