Restart loading takes a few hours, and replication is flawed, how to solve it? Redis Scalable Cluster Setup1. Proactive replication avoids redis replication defects.Since the replication capabilities of Redis are flawed, we might as well abandon the replication capabilities provided by Redis itself, and we can use proactive replication to build our cluster environment. The so-called active replication refers to the data of Redis stored by the busines

This paper introduces the implementation of a scalable TCP service based on Qt. This implementation is built for c/sclient-service cluster application requirements.Connection monitoring, data transmission, and data processing are carried out in a separate thread pool, depending on the specific task, the number of threads responsible for listening, transmitting, and processing can be arranged so as to achieve a trade-off between high transmission load

Apache Thrift-Scalable cross-language service development FrameworkApache Thrift is an efficient framework for Facebook to implement remote service calls that support multiple programming languages. This article will detail the architecture, development, and deployment of Apache Thrift from the Java developer perspective, and give the corresponding Java instance for different transport protocols and service types, and introduce the implementation of T

Design, deploy, and manage a scalable e-commerce website using Windows DNAWhat we want to learn today is the best practice about scalability, availability, and reliability. We will discuss load balancing and optimization of your site, how to use Security Manager to protect your site, and how to analyze your site traffic. So today we need to involve a lot of content.Our course is to provide an overview of Windows DNA at a height of 50,000. We will disc

machine) and scale (scale horizontally, distribute loads on more than one smaller machine) between two options. In fact, a good architecture usually involves a practical hybrid approach: for example, using several powerful machines is still simpler and cheaper than a large number of small virtual machines. Uncontrolled distribution adds complexity to the system, which is a dangerous part of software engineering, although it is fairly straightforward to distribute stateless services on multiple

Protect code blocks with Reentrantlock.Lock lock = new Reentrantlock (); Lock.lock (); try { //Update object state}finally { lock.unlock ();}In addition, the implementation of contention is more scalable than the current synchronized implementation ReentrantLock . (in future versions of the JVM, the contention performance of synchronized i

This example comes from the fifth chapter of Java concurrency Programming. This article will develop an efficient and scalable cache, starting with the simplest hashmap, then analyzing its concurrency flaws and fixing it step-by-step.HashMap versionFirst we define a computable interface that contains a compute () method, which is a long-time numerical calculation method. Memoizer1 is the first version of the cache, which uses HashMap to save the resul

XML scalable style single languageXSL is a language that converts XML documents and then shows the conversion results. The conversion process is to use XSLT (XML Transformations) to convert an XML document to a tree structure (result tree) based on the XML document features. This tree contains style information. Then, follow the analysis result tree of the FO (Formatted object) to present the XML document.XSL represents the two steps of the XML docume
