I. Introduction of Madlib 　　 Madlib is an open-source machine learning Library in collaboration with the University of Berkeley, which provides accurate data parallel implementations, statistics and machine learning methods for analyzing structured and unstructured data, with the main purpose of extending the analytical capabilities of the database, which can be easily loaded into the database. Extended database analysis capabilities, July 2015 Madlib became the Apache Software Foundation incuba

The robust and scalable architecture of HadoopCurrently, there are several main types of SQL on Hadoop products:Hive, Tez/stinger, Impala, Shark/spark, Phoenix, Hawq/greenplum, hadoopdb, Citusdata, etc. This article focuses on the features and latest developments of Hive, Tez/stinger, Impala, shark, and the t

complete whole and are mutually dependent. Of course, what I have to say is that hadoop is also developed by Google based on the principle of mapreduce. However, Google's contribution to open thinking is often limited to the form of papers, and there is little information about its own technical architecture. In fact, in addition to the two heavyweight distributed computing frameworks, there are also some complete solutions that fully utilize the existing open-source database, such as the Bi s

a distributed file system as the basic platform for storing computing data. Of course, both pre-computing and post-computing data are organized through modules such as BigTable and Hbase. The three constitute a complete whole and are mutually dependent. Of course, what I have to say is that Hadoop is also developed by Google based on the principle of MapReduce.

As you know, Apache Spark is now the hottest open source Big Data project, and even EMC's specialized data pivotal is starting to abandon its more than 10-year-old Greenplum technology to spark technology development, and from the industry as a whole, Spark fires are only as much as OpenStack in the IaaS world. So this article as a technical article, we then directly into its core mechanism it. What is memory technology? about memory computing, like c
