This is a creation in Article, where the information may have evolved or changed. Golang is proven to be ideal for concurrent programming, and goroutine is more readable, elegant, and efficient than asynchronous programming. This paper presents a pipeline execution model for Golang implementation, which is suitable for batch processing of large amount of data (ETL) scenarios. Imagine an application scenario like this:(1) Load user reviews from databas

Project Background Shaoxing county is the first pilot city of Digital Urban Management in Zhejiang Province and the first county-level city in China. As the economy develops rapidly, the pace of urbanization accelerates, and the scale of the city expands and the degree of modernization continues to increase, the underground pipelines of the city, as an important urban infrastructure, are becoming increasingly large and intensive, the types of pipelines are becoming more and more complex. The pi

module's granularity, and each module can be reused, which is greatly enhanced by reusability. This pattern is the pipeline pattern to be discussed in this section.As the name implies, the pipeline mode is like a pipe to connect multiple objects, the overall look like a number of valves nested in the pipeline, and the processing logic placed on the valve, such a

I. Concept: interprocess communication ( IPC,interprocess communication) Each process has a different user address space, and the global variables of any process are not visible in the other process, so the exchange of data between cities must pass through the kernel,In the kernel to open a buffer process 1 data from the user space copied to the kernel buffer, process 2 and then read the data from the kernel buffer, the mechanism provided by the system becomes inter-process Communication (IPC,in

A pipeline is one-way, first-out, which connects the output of one process with the input of another. One process (write process) writes data at the end of the pipeline, and another process (read process) reads the data from the head of the pipe. Once the data is read by a process, it will be removed from the pipeline and other read processes will no longer be ab

The implementation principle of this projectsevice only sends data to the pipeline (the data pool), waits for the data in the pool, and it automatically comes to you. You don't have to care about how data is sent and received, just focus on the processing of your business. asAdvantages:The pipeline-based implementation is that the message is sent or received only to be sent to the

INTRODUCTION of Aggregate db.collection.aggregate()是基于数据处理的聚合管道，每个文档通过一个由多个阶段（stage）组成的管道，可以对每个阶段的管道进行分组、过滤等功能，然后经过一系列的处理，输出相应的结果。 图来自https://docs.mongodb.com/manual/aggregation/ 官方网 我们通过这张图，可以清晰的了解Aggregate处理的过程 1、db.collection.aggregate()可以多个管道，能方便的进行数据的处理

Httpmessagehandler PipeIn the Web API, Microsoft has implemented a pipeline design----httpmessagehander (in fact, WCF has a similar architecture) for better architecture expansion.The heads and tails in the entire pipeline are Httpserver, Httproutingdispatcher, and they all inherit Httpmessagehandler, where ASP. NET provides us with an extensible delegatinghandler, Let's take a look at a couple of classes b
