Principal component Analysis PCA1. Basic Ideas
Principal component Analysis (PCA) is a kind of reduced-dimension method for continuous variables, which can maximize the interpretation of data variation, reduce

, because receiver is started by Receiversupervisor, In turn, receiver will store data via Receiversupervisor after receiving the data.The stored meta-data is then reported to the driver side.V: Is driver, manipulating metadata through metadata pointers, manipulating the specific data content on other machines based on the pointer address, and showing the results
entities through its read and write operations. This means that you can make adjustments to the current kernel behavior by modifying the files in the/proc. Then we can release the memory by adjusting the/proc/sys/vm/drop_caches. The operation is as follows:Cat/proc/sys/vm/drop_caches Viewing default valuesTo perform the sync command manually, the Sync command writes all the non-writable system buffers to disk, including modified I-node, deferred block I/O, and read-write mapping files.# echo 3
What is a data structure?Effective management mechanisms for large amounts of data. There are many types of data structures used when describing computer algorithms:Arrays: Data structures for continuous arrangement of data, with data
, 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 solu

For data analysis, I believe that every enterprise that uses the information system has its own understanding. Some of them come from books, some from work experience, and some from software supply. However, enterprises and information systems I know have different definitions of data reports and basic understanding of
