Welcome to the third course in the Big Data Specialization. This week you will be introduced to basic concepts in big data integration and processing. You will be guided through installing the Cloudera VM, downloading the data sets to be used for this course, and learning how to run the Jup...
Big data processing tool and systems 上面是 big data 的3层结构, 系列课程的整个course 2就是讲最底层的 data management and storage 的. 第二层就是这个course 3 主要讲的内容 Redis, AeroSpike- key value storage Lucene Gephi- vector and graph data storage Vertica, Cassadra, HBase- column store ...
flatMap transfromation, 一对多 map 和 flatMap 是narrow tranformation. narrow transformation 只依赖于一个partition上的数据,并且 data suffering is not nessary. Filter transformation Coalesce transformation, 比如 上面谈的都是narrow transformation, 都是本地处理数据不需要在网络上传输数据。 接下来谈wide tran...
2. Integration and Processing Requirements Aside from storage challenges, big data also has to be properly processed, cleaned and formatted to make it useful for analysis. This can take a considerable amount of time and effort due to big data’s size, multiple data sources and combinations of ...
