Google’s MapReduce programming model serves for processing large data sets in a massively parallel manner. We deliver the first rigorous description of the model including its advancement as Google’s domain-specific language Sawzall. To this end, we reverse-engineer the seminal papers on MapReduce...

HDFS is one of the major components of Apache Hadoop, the others being MapReduce and YARN. ZFS is an enterprise-ready open source file system and volume manager with unprecedented flexibility and an uncompromising commitment to data integrity. OpenZFS is an open-source storage platform. It ...
Pregel是由 Google 提出的一个专门用于大规模图计算的分布式系统框架,旨在高效处理超大规模图数据,如社交网络、Web 图、道路网络等。Pregel 的设计受 Google MapReduce 成功经验的启发,但针对图计算场景优化,解决了如图遍历、最短路径、图划分等问题。 产生背景 ...
Cloud Dataflow also handles massive, multipetabyte data sets and has essentially replaced MapReduce internally for Google. MapReduce is no longer supported by Google, so it encourages MapReduce customers to migrate to Cloud Dataflow, and provides assistance with the process. Cloud Dataproc is Google...

The following paragraphs describe the MapReduce programming model and an implementation of the model for processing and generating large data sets. The model and its library implementation will both be referred to as MapReduce. Using MapReduce, programmers specify a map function that processes a key...
