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

This is another way to manage queues and worker clusters. Storm can also be used for "continuous computing" (continuous computation), which make

ObjectiveThis article focuses on springboot integration of Kafka and Storm and some of the problems and solutions encountered in this process.Knowledge of Kafka and StormIf you are familiar with Kafka and Storm , this section can be skipped directly! If you are not familiar, you can also look at the blog I wrote earlier. Some of the related blogs are as follows.Environment installation for Kafka and StormAd

Static calls in C # C++dll and C # in dynamic call C++dllIn recent projects, involving the project source code security issues, because the code is written in C #, easy to be anti-compilation, so decided to extract the core algorithm is written in C + +, C + + so far seems not to be very good anti-compilation, of course, if you are an anti-assembly master, it may be possible to decompile. In this way, it involves invoking C # managed code with C + + u

This blog post details how to install the Storm local development environment, which consists of two steps: 1. Download the Storm release package from the official website, decompress the package, and add the decompressed bin directory to the environment variable (PATH, to facilitate subsequent execution of Storm-related commands 2. Modify the

I. Description　　Storm is a distributed real-time computing system, and Storm's significance for real-time computing is equivalent to the meaning of Hadoop for batch computing. For a system with high real-time storm is a good choice. Hadoop provides a map, reduce primitive, which makes the batch process very simple and graceful. In the same way, Storm provides som

Description: This article translates the Storm Code structure Description section of structure of the codebase, available from Storm's official wiki on GitHub, to help friends who are based on Storm's source-level learning and research.Storm's source code is divided into three different levels.First, Storm was designed to take into account the compatibility of multilingual development. Nimbus is a thrift se

Hadoop (the undisputed king of the Big Data analysis field) concentrates on batch processing. This model is sufficient for many scenarios, such as indexing a Web page, but there are other usage models that require real-time information from highly dynamic sources. To solve this problem, you have to rely on Nathan Marz's Storm (now called Backtype in Twitter). Storm does not process static data, but it handl

Sometimes you may want to develop a Storm project in a language that is not based on JVM. You may prefer to use other languages or libraries written in a language. Storm is implemented in Java. All the spouts and bolts in this book are written in java. It is possible to use languages such as Python, Ruby, or JavaScript. Sometimes you may want to develop a Storm p

1. The proposed storm transactional topologyFor a fault-tolerant mechanism, storm uses a system-level component Acker, combined with an XOR check mechanism, to determine whether a MSG is sent successfully, and then spout to resend the MSG to ensure that a MSG is re-sent at least once in the case of an error. However, in some scenarios where transactional requirements are high, it is necessary to guarantee o

1. transaction-Batch ProcessingFor the fault-tolerant mechanism, storm passes a system-level component Acker, combining the XOR check mechanism to determine whether a tuple is sent successfully, and spout can resend the tuple to ensure that a tuple is re-sent at least once in the case of k\ error.However, when you need to accurately count the number of tuples, such as the sales amount scenario, you want each tuple to "be processed only once".

Data acquisitionresponsible for collecting data in real time from each node and choosing Cloudera Flume to realize2).

Feng Xin, CEO of storm audio and video, has been sleeping for the last half month. This will start half a month ago. On the evening of October May 18, a series of data streams on the Chinese Internet began to flow in the same direction. The DNSpod server, which provides domain name resolution services for many websites, has suffered an unprecedented blow. Domain Name requests over 10 Gbps attack the data center like crazy.

topology-workers parameter specifies the number of workers to be started by a topology runtime.2. Parallelism-hint specifies the number of initial executor for a component (component, such as spout).3, Topology-tasks is the tasks of component, calculate a little more complex points:(1). If topology-tasks is not specified, this value is equal to the initial executors number.(2). If specified, compare with topology-max-task-parallelism value and take the small one as the actual topology-tasks.To
