/reduce can also be seen along these two processes.In the Map/reduce framework, each calculation request is called a job. In the distributed Computing Map/reduce Framework, in order to complete this job, it carries out a two-step strategy, the first is to split it into a number of map tasks, assigned to different machines to execute, each map task takes a part of the input file as its own input, after some

addition to an independent topic, resulting in a series of real-time data processing processes. Strom and Samza are very famous for implementing this type of data conversion framework. 6. Event Source An event source is an application-designed way in which state transitions are recorded as sequential sequences of records sorted chronologically. Kafka can store a lot of log data, which makes it an excellent background for applications in this way. such as dynamic totals (news feeds). 7. Persiste

these open source solution for me to use, if necessary to modify the source code, which is difficult to estimate the cost, There is also a risk that if the choice of open source solution in the future will find some features are not satisfied, it will have to be overturned; if independent research and development, the project development cycle will be extended, and seems to have repeated the suspicion of making wheels. For open source tools, important open source tools include Zookeeper,solr,op

Service consumers, from the provider address list, based on the soft load equalization algorithm, select a provider to invoke, if the call fails, then select another call. 5. Service consumers and providers, in the memory of the cumulative number of calls and call time, timed every minute to send statistical data to the monitoring center. second, build distributed development
