Redis Server Memory Usage

Using Redis to develop applications is a pleasant process, but as with other technologies, you need to remember a few things as well, based on Redis application design. Before, you might have a chest of the whole pattern of relational database development, and REDIS application development has many similarities, but you have to keep in mind that the following two points--redis is a memory database, and it is single-threaded. Therefore, when using Redis, you need to pay attention to the following points: 1. Master all key databases stored in Redis ...

The recently publicly previewed Azure Redis cache is easily integrated into your Azure Web site application, where I integrate the MVC Movie sample program into Azure Redis cache and deploy it to azure Web services (Websites), about a few About 15 minutes. After the cache is imported, the program is nearly 100 times times faster than the pure database because the data that is often accessed can be obtained directly from the cache ...

It was easy to choose a database two or three years ago. Well-funded companies will choose Oracle databases, and companies that use Microsoft products are usually SQL Server, while budget-less companies will choose MySQL. Now, however, the situation is much different. In the last two or three years, many companies have launched their own Open-source projects to store information. In many cases, these projects discard traditional relational database guidelines. Many people refer to these items as NoSQL, the abbreviation for "not only SQL." Although some NoSQL number ...

Instagram is a model for many startups, with more than 10 of companies, from the beginning of obscurity to the end of a hefty takeover by Facebook. How does a company, from the beginning of the operating system selection, server to database selection, message push, how to do? This article compiles from the Instagram engineering blog, tells you Instagram technical secret. When choosing a system, our core principles are: Try to be as simple as possible, do not do repetitive work, and try to adopt proven technology. Operating system/Hosting because we were only three.

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the distributed features of the NoSQL database ...

Naresh Kumar, a software engineer and enthusiastic blogger, has great interest in programming and new things, and is happy to share technical research results with other developers and programmers. 　　Recently, Naresh wrote about 12 well-known free, open source NoSQL databases, and analyzed the characteristics of these databases. Now that the NoSQL database is becoming more and more popular, I'm here to summarize some of the great, free and open source NoSQL databases. In these databases, MongoDB the top, with considerable ...

Web site performance is an objective indicator, can be reflected in response time, throughput, concurrency, performance counters and other technical indicators. 1. Performance Test Indicator 1.1 response time refers to the time that the application takes to perform an operation, from the time it takes to send the request to the final receipt of the response data. The following is a list of common operational response schedules for the system. Operation Response time Open a website a few seconds database query a record (has index) more than 10 milliseconds machine ...

(Author Srini penchikala translator Dingxuefeng) for non-relational data types such as documents, object graphs, and key-value pairs, the NoSQL database provides them with an alternative way to store data. Can distributed caching be used as a NoSQL database? Ehcache's Greg Luck author describes the similarity between distributed caching and NoSQL databases. Infoq interviewed him and discussed the pros and cons of the scheme. InfoQ: Can you do a distributed caching solution with the NoSQL database ...

The architectural challenges behind the tumblr:150 of billions of months of browsing are the same as many emerging websites, where the famous light blogging service Tumblr is facing the bottleneck of the system architecture in the rapid development. 500 million times a day, peak 40,000 requests per second, 3TB of new data storage, more than 1000 servers, in this case how to ensure the smooth operation of the old system, smooth transition to the new system, Tumblr is facing enormous challenges. Tumblr was very typical of lamp applications. is currently evolving to a distributed service model based on SCA ...

"Editor's note" in the famous tweet debate: MicroServices vs. Monolithic, we shared the debate on the microservices of Netflix, Thougtworks and Etsy engineers. After watching the whole debate, perhaps a large majority of people will agree with the service-oriented architecture. In fact, however, MicroServices's implementation is not simple. So how do you build an efficient service-oriented architecture? Here we might as well look to mixrad ...
