Programming Model MapReduce 的模型原理是:对 input key/value pairs 对进行处理,生成对应的 output key/value pairs,这两步通过 Map 函数和 Reduce 函数来完成。 Map:由用户编写,接受一个 input key/value pair ,生成一个 intermediate key/value pairs 的集合,MapReduce Libray 将所有具有相同 intermediate key...
MapReduce:In 2004, Google shared the MapReduce programming model that simplifies data processing on large clusters. The Apache Hadoop project is an open source implementation of the MapReduce algorithm that was subsequently created by the community. BigTable:In 2006, Google introduced the BigTable d...
2019年6月份起，按照之前的设想，开始在工作时间之外筹划NascentCore。这个项目借鉴了MapReduce、Spark、Mesos等分布式计算领域的开源项目；以及我在Amazon和Google积累的观察和研究。NascentCore是一个面向Kubernetes平台的原生的分布式编程框架（Natively Distributed Programming Framework），目标是免除分布式应用在集群上的运维...
