Master Slave Database Architecture

MySQL master-slave synchronization is a very mature architecture, the advantages are: ① from the server can perform the query (that is, we often say reading function), reducing the pressure on the main server; ② in the backup from the main server to avoid the impact of the backup Main server service; ③ When the main server problems, you can switch to the server. So I often use this program in the deployment and implementation of the project; In view of the mysql production environment rigor, I recommend Zhang fellow MySQL source compiled here. The fourth edition updated as follows: First, an increase of ...

The concept of blockchain to technology has been around for a long time, but with the heat of the past two years, it has gradually become known by the market and many technicians.

As the most popular open source database, MySQL is widely used in Web applications and other small and medium-sized projects. However, in many large IT companies, MySQL has gradually deviated from the original open source version after being highly optimized and customized, more like a branch, such as the Webscalesql of Facebook, which was not long ago open source. 　　Recently, Mr. Xiong has published a blog post, from the perspective of large-scale web site architecture development of the changes in MySQL application, here for you to share. This article mainly describes the different and ...

As a software developer or DBA, one of the essential tasks is to deal with databases, such as MS SQL Server, MySQL, Oracle, PostgreSQL, MongoDB, and so on. As we all know, MySQL is currently the most widely used and the best free open source database, in addition, there are some you do not know or useless but excellent open source database, such as PostgreSQL, MongoDB, HBase, Cassandra, Couchba ...

Game Architecture Analysis-game Cloud series five talk about architecture, divided into two, one is the software level of the Code architecture, and the other is the hardware level of the system architecture. Software level, module division, Code reconfiguration and business layer architecture. System level, to network, deployment, server cluster-oriented. The architecture of software hierarchy lies in the development of early code. Hardware-level system architecture, in the late deployment of the server online.   Today's content is primarily biased towards the system architecture in the gaming domain. Talk about system architecture, no outside of those technologies, what load balance ah, what database ...

Speaking of architecture, divided into two pieces, one is the software level of the Code architecture, and the other is a hardware-level system architecture. Software level, module division, Code reconfiguration and business layer architecture. System level, to network, deployment, server cluster-oriented. The architecture of software hierarchy lies in the development of early code. Hardware-level system architecture, in the late deployment of the server online.   Today's content is primarily biased towards the system architecture in the gaming domain. Talk about system architecture, no outside of those technologies, what load balance ah, what database vertical, horizontal partition Ah, front-end/back-end cache ...

The storage system is the core infrastructure of the IT environment in the data center, and it is the final carrier of data access. Storage in cloud computing, virtualization, large data and other related technologies have undergone a huge change, block storage, file storage, object storage support for a variety of data types of reading; Centralized storage is no longer the mainstream storage architecture of data center, storage access of massive data, need extensibility, 　　Highly scalable distributed storage architecture. In the new IT development process, data center construction has entered the era of cloud computing, enterprise IT storage environment can not be simple ...

After more than eight years of practice, from Taobao's collection business to today to support all of Alipay's core business, and in the annual "Double Eleven Singles Day" continue to create a world record for the transaction database peak processing capacity.

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...

Through the introduction of the core Distributed File System HDFS, MapReduce processing process of the Hadoop distributed computing platform, as well as the Data Warehouse tool hive and the distributed database HBase, it covers all the technical cores of the Hadoop distributed platform. Through this stage research summary, from the internal mechanism angle detailed analysis, HDFS, MapReduce, Hbase, Hive is how to run, as well as based on the Hadoop Data Warehouse construction and the distributed database interior concrete realization. If there are deficiencies, follow-up ...
