CRS can be used as caching, in session caching, full-page caching, improving database query performance, and other scenarios have a significant advantage; CRS can also be used as a key-value store with high reliability of data that can generate Lengbei and log back through the logs on a daily basis. In the rankings, counter applications, real-time systems, after reading that burning needs to accurately set the expiration time of the application, anti-

What is serialization?Program apes in writing applications often need to store some of the program's data in memory, and then write it to a file or transfer it to a network on a computer for communication. The process of converting program data into a format that

1. OverviewWhen we consider the highly available architecture of the MySQL database, we mainly consider the following aspects:1.1 If the database is down or an unexpected outage, and so on, can restore the availability of the database as soon as possible to reduce downtime, to ensure that the business will not be interrupted due to database failure.1.2 Data for non-primary nodes that are used as backups, read replicas, and so on, should be in real-time or eventually consistent with the master no

the feeling that his program was used by tens of thousands of people, and it was obvious that he did it;In January 2008, Hadoop became an open source project for Apache.The advent of Hadoop solves the massive data storage and processing in the internet era, which is a framework system that supports distributed computing and storage. If the Hadoop cluster is abstracted into a single machine, theoretically our hardware resources (CPU, memoery, etc.) can be infinitely extended.Hadoop extends its a

Introduction to cache micro-Application Experience in Distributed Systems (iv) [interactive scenarios] Preface I have been busy with things in recent months, and I have never been idle for almost years. Busy in the middle of the fall of 2018, I have to sigh that time is always blank, and I do not know what I have gained or lost. I recently took a break and bought two books unrelated to technology. One was the high mountains of Portugal written by Y

This example is just a few small practices that bloggers learn to block queues and post, not real application scenarios!The producer consumer scenario is the most common scenario in our application, where we can implement producer and consumer scenarios through reentrantlock condition and thread wait,notify and communication to achieve multi-producer and multi-consumer patterns, The latter can only achieve

One of the great advantages of Redis is the ability to use databases such as MySQL, rather than the entire database, to improve efficiency only in certain scenarios through Redis's features. This article lists 11 such web scenarios, such as displaying the latest list of items, deleting and filtering, leaderboards, and other related requirements."51CTO featured Translations" in the "How to make Redis work in

Introduction Data mining software IBM SPSS Modeler is known for its user-friendly, visually powerful features. There are few references to its scripting features. The author believes that the scripting function is actually designed to automate the process of data processing and analysis modeling. In scenarios where data processing needs to be dynamically changed, automatic execution of streams, and automatic execution of batch tasks, some scripts mus

The singleton mode (Singleton) is also called the single-state mode, is the simplest mode in the design pattern, even some model masters do not call it a pattern, called it as a realization technique, because the design pattern emphasizes the abstraction of the relationship between objects, and the singleton pattern only has its own object, So there are some design masters and call it one of the design patterns. Here is not specifically how to implement the singleton mode and introduce its princ

free,auto-sharding and so on. For example, some common document databases are supported Schema-free, directly store JSON format data, and support auto-sharding functions such as MongoDB. In the face of these different types of nosql products, we need to choose the most suitable products according to our business scenarios. Redis is most suitable for all data in-momory scenarios, although Redis also provi
