Original address The idea of real-time business intelligence is no longer a novelty (a page on this concept appeared in Wikipedia in 2006). However, although people have been discussing such schemes for many years, I have found that many companies have not actually planned out a clear development idea or even realized the great benefits. Why is that? One big reason is that real-time business intelligence and analytics tools are still very limited on the market today. Traditional Data Warehouse e
When you start writing Apache Spark code or browsing public APIs, you will encounter a variety of terminology, such as Transformation,action,rdd and so on. Understanding these is the basis for writing Spark code. Similarly, when your task starts to fail or you need to understand why your application is so time-consuming through the Web interface, you need to know
An important reason Apache Spark attracts a large community of developers is that Apache Spark provides extremely simple, easy-to-use APIs that support the manipulation of big data across multiple languages such as Scala, Java, Python, and R.This article focuses on the Apache

Currently, Apache Spark supports three distributed deployment methods, standalone, spark on Mesos, and Spark on YARN, the first of which is similar to the pattern used in MapReduce 1.0, where fault tolerance and resource management are implemented internally. The latter two are the trend of future development, partial

The high performance of Apache Spark depends in part on the asynchronous concurrency model it employs (this refers to the model used by the Server/driver side), which is consistent with Hadoop 2.0 (including yarn and MapReduce). Hadoop 2.0 itself implements an actor-like asynchronous concurrency model, implemented in the epoll+ state machine, while Apache

When it comes to big data, I believe you are not unfamiliar with the two names of Hadoop and Apache Spark. But we tend to understand that they are simply reserved for the literal, and do not think deeply about them, the following may be a piece of me to see what the similarities and differences between them.1, the problem-solving level is not the sameFirst, Hadoop and A
