Feed: Cloudera Engineering Blog » Hadoop. Author: Matt Massie. We asked Brian Bockelman, a Post Doc Research Associate in the Computer Science & Engineering Department at the University of Nebraska–Lincoln, to tell us how Hadoop is being used to process the results from High-Energy Physics experiments.  His response gives insights into the kind and volume of data that High-Energy Physics experiments generate and how Hadoop is being used at the University of Nebraska. -Matt In the least technical language, most High Energy Physics (HEP) experiments involve colliding highly energetic, common particles together in order to create small, exotic, and incredibly ...

Feed: IBM Big Data & Analytics Hub - All Content. Author: cindy-russell. It seems that we’re reaching the point where the Internet of Things (IoT) is moving from the domain of enthusiastic early-adopters to the more challenging, more profitable territory of mainstream enterprise technology.In particular, companies in industries that depend on the attention and loyalty of large numbers of consumers – retail and air travel, for example –have already woken up to the possibilities. If you can recognize an individual customer’s mobile device as they move through an airport or walk past your store, you can potentially take action to improve that ... Read More

Feed: Planet big data. Author: David Smith. R is incredible software for statistics and data science. But while the bits and bytes of software are an essential component of its usefulness, software needs a community to be successful. And that's an area where R really shines, as Shannon Ellis explains in this lovely ROpenSci blog post. For software, a thriving community offers developers, expertise, collaborators, writers and documentation, testers, agitators (to keep the community and software on track!), and so much more. Shannon provides links where you can find all of this in the R community: #rstats hashtag — a responsive, ... Read More

Feed: AWS Compute Blog. Author: Juan Villa. Juan Villa – Partner Solutions Architect When most people hear “Java” they think of Java the programming language. Java is a lot more than a programming language, it also implies a larger ecosystem including the Java Virtual Machine (JVM). Java, the programming language, is just one of the many languages that can be compiled to run on the JVM. Some of the most popular JVM languages, other than Java, are Clojure, Groovy, Scala, Kotlin, JRuby, and Jython (see this link for a list of more JVM languages). Did you know that you can ...

Feed: Planet MySQL. Author: Wagner Bianchi. Most of the time when you start a database design you don’t imagine how your applications need to scale. Sometimes, you need to shard your databases among some different hosts and then, on each shard you want to split reads and writes between master and slaves. This blog is about MariaDB MaxScale being able to handle different databases across shards, and splitting up reads and writes into each of the shards to achieve the maximum level of horizontal scalability with MariaDB Server. After reading this blog you will be able to: Know how MariaDB ... Read More

Feed: Cloudera Engineering Blog » Hadoop. Author: Aaron Kimball. You might think that the SecondaryNameNode is a hot backup daemon for the NameNode. You’d be wrong. The SecondaryNameNode is a poorly understood component of the HDFS architecture, but one which provides the important function of lowering NameNode restart time. This blog post describes how to configure this daemon in a large-scale environment. The default Hadoop configuration places an instance of the SecondaryNameNode on the same node as the NameNode. A more scalable configuration involves configuring the SecondaryNameNode on a different machine. About the SecondaryNameNode The NameNode is responsible for the ... Read More

Feed: Percona Database Performance Blog. Author: Vadim Tkachenko. Vadim Tkachenko  | June 22, 2017 |  Posted In: Benchmarks, MySQL, Performance Schema PREVIOUS POST In this blog post, we’ll look at how ClickHouse performs in a general analytical workload using the star schema benchmark test. We have mentioned ClickHouse in some recent posts (ClickHouse: New Open Source Columnar Database, Column Store Database Benchmarks: MariaDB ColumnStore vs. Clickhouse vs. Apache Spark), where it showed excellent results. ClickHouse by itself seems to be event-oriented RDBMS, as its name suggests (clicks). Its primary purpose, using Yandex Metrica (the system similar to Google Analytics), also points to ... Read More
