Not on the current edition
This blip is not on the current edition of the Radar. If it was on one of the last few editions it is likely that it is still relevant. If the blip is older it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar Understand more

试验 ? 值得一试。了解为何要构建这一能力是很重要的。企业应当在风险可控的前提下在项目中尝试应用此项技术。

Apache Spark has been steadily gaining ground as a fast and general engine for large-scale data processing. The engine is written in Scala and is well suited for applications that reuse a working set of data across multiple parallel operations. It’s designed to work as a standalone cluster or as part of Hadoop YARN cluster. It can access data from sources such as HDFS, Cassandra, S3 etc. Spark also offers many higher level operators in order to ease the development of data parallel applications. As a generic data processing platform it has enabled development of many higher level tools such as interactive SQL (Spark SQL), real time streaming (Spark Streaming), machine learning library (MLib), R-on-Spark etc.

评估 ? 在了解它将对你的企业产生什么影响的前提下值得探索

For iterative processing such as machine learning and interactive analysis, Hadoop map-reduce does not work very well because of its batch-oriented nature. Spark is a fast and general engine for large-scale data processing. It aims to extend map-reduce for iterative algorithms and interactive low latency data mining. It also ships with a machine learning library.
