cause and effect are doing well (Fuxing technology, DE Shaw ), however, companies with profound financial theories and poor big data analysis capabilities do not have similar performance. MIT financial expert Luo Wenquan admitted that he does not understand what Renaissance technology is doing.Hey, let's talk about you. Don't keep an eye on people with an annual

The heat of big data continues to rise, and big data has become another popular star after cloud computing. We're not going to talk about whether big data works for your company or organization, at least on the internet, which has

operational data; Instead, users analyze past product sales, forecast trends, and determine future customer purchase patterns by querying data. Big data applications are often not positioned as critical business systems, although they also support sales and marketing decisions, but do not significantly affect core bus

, Python and other development tools, run the script language Automation cluster deployment, management and monitoring, master the installation of common set up, optimization , improve the overall performance and be familiar with the data center security policy.Big data is a need to master a lot of knowledge of the field, the General people who choose these several directions. As programmers, transferring t

develop a new system that allows more companies to leverage big data analytics tools and the industrial Internet, the latter being a complex network of physical machinery.This new system is called the "Industrial data Lake", which combines the Predix industrial software platform and the open source software framework

hours to 8 seconds, while MkI's genetic analysis time has been shortened from a few days to 20 minutes.Here, let's look at the difference between MapReduce and the traditional distributed parallel computing environment MPI. MapReduce differs greatly from MPI in its design purpose, usage, and support for file systems, enabling it to be more adaptable to processing needs in big data environments.What new met

To be able to better architect big data projects, here to organize, for technicians, project managers, architects to choose the right technology, understand

have no experience with Hadoop technology. The number of people who know SQL is 100 times times more than Hadoop. Solutions like splice Machne, PRESTO,IBM Big Data, Oracle Big Data SQL, and so on, which provide a way to query big

- source implementation that mimics Google's big Data technology is:HadoopThen we need to explain the features and benefits of Hadoop:(1) What is Hadoop first?Hadoop is a platform for open-source distributed storage and distributed computing .(2) Why is Hadoop capable of distributed storage and distributed computing? This is because Hadoop consists of two core components:HDFs: A Distributed File

: Architecture: Impala Technology is currently performing well, discarding the mapreduce design, combined with the HDFS cache can do better performance Maturity: more mature Efficiency: With parquet, performance is close to Hive+tez because it does not need to be started at a certain level of analysis faster than hive Learning curve: Learning SQL and Impala itself, so the difficulty is general. Summarize: Impala has a good performance, but on

, such as cloud computing, cloud storage technology, their rapid development, is the birth of big data hotbed, without these technologies, even if there is a large number of data can only feel powerless. Traditional storage technology is relatively backward, according to different data implementation of a single storag

removed during the data preparation process, and due to the large amount of data, a small number of rows with missing values are cleared, and data sets that are easily analyzed and plotted are reconstructed.4. Data analysis1. Analysis of the distribution of big

thought that the company would guide producers, starring selection and screenwriter content and hit the market by analysing big data on their accumulated years of user-viewing preferences, helping them get millions of new users in a quarter and gaining several times the price increase over the next year or two.Four challenges to building a big

, the project covers almost all the functional points, knowledge points, and performance optimization points in the three technical frameworks of Spark Core, spark SQL and spark streaming. With just one project, you can get a complete grasp of how spark technology can meet all types of business needs in real-world projects! In the project, focus on the real enterprise projects accumulated valuable performance tuning, troubleshooting and data tilt
