HBase is an open-source, scalable, distributed NoSQL database for massive data storage that is modeled on the Google BigTable data model and built on the HDFs storage system of Hadoop. It differs significantly from the relational database MySQL, Oracle, etc., and HBase's data model sacrifices some of the features of the relational database, but in exchange for great scalability and flexible operation of the table structure. To a certain extent,

From a statistical point of view, the requirements of these business functions can be summed up as: 1 statistical indicators of the calculation, such as PV, UV, IP, etc., can be summed up to a piece of data for SUM, AVG and other operations. 2) The demand of statistics is more and more real-time, and the source and source are diversified. For this kind of demand, no statistical calculation, but to be preprocessed qu

From a statistical perspective, the requirements for these business functions can be summarized: 1) Calculation of various statistical indicators, such as PV, UV, and IP, can be attributed to operations such as sum and AVG for one piece of data. 2) the demand for statistics is increasingly demanding for real-time performance. Access sources occur anytime, anywh

Ganglia is an open-source monitoring project initiated by UC Berkeley designed to measure thousands of nodes. Each computer runs a gmond daemon that collects and sends metric data (such as processor speed and memory usage. It is collected from the operating system and the specified host. Hosts that receive all metric data can display the data and pass the simplified form of the data to the hierarchy. Ganglia can be well expanded just because of this hierarchical structure. Gmond has very little
