NoSQL Selection and HBase case

Next, Wang Shupeng, associate researcher of Institute of Information Engineering, Chinese Academy of Sciences, shared the development and use of new NoSQL large data management systems (BDMS). Wang Shupeng said most of the projects he contacted were non-Internet applications, such as security and transportation.   These industries are now faced with big data, but many popular NoSQL databases do not apply to them, so they independently developed a NoSQL database management system. The design of the target system is highly scalable: it can be achieved by increasing the linear branch of the node ...

Hadoop serialization and Writable interface (i)

Serialization serialization (serialization) is the process of converting a structured object into a byte stream so that it can be transmitted over a network or written to a hard disk for permanent storage, and a relative deserialization (deserialization) refers to the flow of bytes back to the structured object. In a distributed system, the process serializes objects into a byte stream, travels over the network to another process, and another process receives a stream of bytes, which, by deserializing, returns to the structured object to achieve interprocess communication. In Hadoop, Mapper,combi ...
