originally stored on. When a value is obtained, the client obtains the same hash value from the key and selects the same server for the information. If you use the same list of servers on each application server (and in the same order), each application server will select the same server when you need to save or retrieve the same key. Now, in this example, 3GB of memcached space can be shared rather than replicated in the same 1 GB space, which brings more cache available and is likely to impro

I wanted to write without writing because the Dynamic Data source switch is resolved, but cannot be added dynamically, and adding a new data source requires restarting the Web server. Later this problem solved, but because the business is busy, today, to write this article for a week without turning off the computer. The company's business is this, there are currently nearly 150 db, each DB database library

practical application, we can see that there are several problems in connecting to the database using this method. The first is security. Because the program code contains the user name and password, if others can get bytecode, they can get the user name and password through The Decompilation tool. The second is code portability. If you want to change the name or user name of the connected database, the programmer must modify the source program and then send the modified program to the user. Th

From: http://www.javaeye.com/topic/931843 Implement myibatis dynamic SQL cross-database processingSpring dynamically configures multiple data sources, that is, splitting data in large applications and managing multiple database instances, which can effectively improve the horizontal scalability of the system. This solution is different from the common single

As business changes/requirements change, Java EE applications are forced to connect multiple data sources for business processing.How do you dynamically switch data sources in the most elegant/concise way without affecting the original project structure?This article has once added the

When developing a database-based application system, you must configure the data source in the project to connect to the database for database operations. The methods for configuring data sources for different databases are basically the same. The difference is that the JDBC driver classes and connection URLs of different databases and the corresponding database

Previously, only the paging plug-ins under the single data source were used, and almost no configuration was necessary. A static method can be done.Pagehelper.startpage (Pagenum, pageSize);Later using a multi-data source (different database), the Pagehelper paging plugin needs to set a default database, MySQL, Oracle, or other.However, it is not possible to switch in real-time, resulting in requests for the

This is the problem I encountered. The project uses spring + hibernate + proxool for database connection management and access. The requirement is to dynamically configure and load multiple data sources. The idea is: 1. Implement the applicationlistener interface using a kind of advanceddatasourceinitizer. When the contextrefreshevent event is published, the database configuration is automatically read from

The same project can sometimes involve multiple databases, or multiple data sources. Multiple data sources can be divided into two situations:1) Two or more databases are not relevant, independent of each other, in fact, this can be developed as two projects. For example, in the game development of a database is a plat

With spring data source routing, it seems that there is no way to add data sources directly, but only with reflection.Add user data source in spring Security userdetailservice.loaduserbyusername when user login is successful/* * * Add user data source

Keywords: merge ObservableObjectiveIn Rxjava, it is a common operation to handle multiple observables at the same time. The following is a simple analysis of the next few combinations of the operators of the class.If you don't want to see the operator's introduction, you can skip to the actual combat section of the project.MergeIn the asynchronous world often creates such scenes, we have multiple sources but want only one result: multi-input, single o

Combining with the new features of JBoss EAP 6.2, this paper introduces the features of the JBoss Module declaration container.

JSON is widely used as a lightweight data format, and the need for reports to read JSON data sources for report development is also common. Dry report using a JSON data source requires that the result set be returned to the report after the JSON file is parsed in a custom dataset through a Java program, and the impleme
