learn to manage them, to push them caller, they are too timid to say, you have to summarize their work to show to the important people. (If you can't recruit Chinese, no one will burn coal?) The engine is broken, the ship is very important. You can't burn coal, your ship doesn't matter, with the experience of working on this ship, you can jump to other boats, so you need to meet and focus on important people when you're at work, because their networks can help you find your next boat very quick

APACHE kylin™ OverviewApache kylin™ is an open-source, distributed analytics engine that provides SQL query interface and Multidimensional Analysis (OLAP) capabilities on top of Hadoop to support hyper-scale data, originally developed and contributed by ebay Inc to the open source community. It can query large hive tables in sub-second.What is Kylin?-Extensible hyper-fast OLAP engine:Kylin is designed to reduce the latency of billions of data queries on Hadoop-Hadoop ANSI SQL Interface:Kylin pro

, in addition, it is difficult for users to expand it.It is worth noting that racer, fact, and pellet use the descriptive logic as the theoretical basis,AlgorithmThe tableau algorithm is used. These systems have done a lot of optimization work. Jena is an application development kit for semantic web. It contains comprehensive content, and the inference engine is only part of it. The inference engine provided by Jena is similar to that provided by ra

monotonic nature of the raw data will help you think about the relationships between the variables in the system. In addition to starting from the blank data, wait for inspiration to suddenly enter your consciousness. You can also be more positive, by following these great resources to help you uncover interesting associations: An automatic data visualization tool developed by Charted--medium.

Recently See Git lfs article, read the next introduction, is really good, similar to Git, but a little different oh. If you want to track the files, go ahead. git lfs track *.pdf In the past, when we were in Tableau's big files, we were going to use git, but it would be slow, and maybe Git server would be hung up. Git in version code, will be differ, just make changes to the change record, do not know git lfs binary is how to do, perhaps each file saved a portion, this is simple (and git trea

-threaded algorithm, but Kylin uses a parallel algorithm.User-TOPN queries, such as fetching 100 data, are written as SQL statements as shown in. and Kylin will automatically adapt to such a SQL to directly use the pre-aggregated good results, so at run time Kylin just put the pre-calculated 1000, 10,000 item directly back to the good, there is almost no online calculation, the speed will be very fast.　　7. Integration of analysis tools　　In the new version, Kylin also added some ODBC interfaces,

First of all, I would like to thank Miss Lin Feng for choosing me. @ Kener-Lin Feng (1) Next I will introduce Baidu's data visualization components echarts and zrender.As we all know, the arrival of the big data era not only brings challenges but also opportunities, but it is only a start. The big data era will have a major impact on our lives. As Victor may-schenberger, author of The Big Data age, said, "Today, data has become a commercial capital and an important economic investment, new econo
