MongoDB cluster refactoring, freeing up disk space Because MongoDB does not reclaim the corresponding disk space after deleting some of the data, it frees up disk space by rebuilding the data directory. an experimental environment A replica set is configured, which consists of the following three nodes: 10.192.203.201:27017 PRIMARY 10.192.203.202:27017 Secondary 10.192.203.202:10001 Arbiter Two experimental steps2.1 Simulation Environment Use DBA; fo

maintenance can be easily completed (no matter how many times the software undergoes changes and how many years it is maintained), To ensure that every change in future needs can be easily done (rather than bones). It is not easy to do these things, it requires us to continuously optimize and improve the internal quality of the system. This is the value of the system reconfiguration. In order to effectively improve the internal quality of the software, what should we do in the system

During JavaScript refactoring, I hope to introduce an easy-to-use testing framework to ensure smooth refactoring. In the future, I will continue to use the testing code to ensure the correctness of the JavaScript logic.Http://sourceforge.net/projects/jsunit/,http://www.jsunit.net/ (JsUnit)JsUnit is an independent JavaScript unit testing framework, which is similar to JUnit and has no difficulty in getting s

Code refactoring is sometimes boring. String replacement and other operations are not only boring, but also prone to errors. Fortunately, some tools are available, taking PHP as an example, such as Rephactor, scisr and so on, but the ready-made tools often mean that they are not flexible enough. So today I want to talk about the application of Shell in code refactoring. Let's start with a simple one. If we

Divide and conquerHere are some of the key points of HTML and CSS in the development process.page structure in single page modeIn single-page mode, the concept of weakening HTML, the HTML as a container, body display of the main content is the page, an HTML container can hold 1 or more pages, each page is placed in the section. A page (section) must have a main content (content), or it may contai

C # asynchronous tool class and a little refactoring experience, The first article of the new year in 2015, wishing you a little late, but your sincerity is still at: Happy New Year. Today I want to share an asynchronous tool class. In the C/S architecture, I first perform asynchronous access to network resources and then call the callback function Invoke to the UI thread for UI processing. This is a common scenario. Therefore, a tool class is special

This period of time the message bus was re-refactored. This refactoring mainly focuses on the components of the message bus and the simplification of the pubsub client, as well as some ideas about the message bus. Simplifying the complexity of the clientThe previous client needs to connect two distributed components at the same time. Access to the message bus requires the user to provide the pubsuberHost pubsuberPort parameters, so it first connects

044 refactoring of the module navigation function (2)After analysis, the data types of the first-level navigation can be divided into the following categories: 1, the actual field value of the module: for example, the "province" module, the owning area is a string field, which contains the name of each area.2, the parent module navigation: For example, the "City" module, you can use the province to navigate it.3. Numeric range for a numeric field: You

If you find that a class has done too many simple delegate actions, you can consider whether you can allow the client to invoke the Trustee class directly. In hide delegate, we describe the benefits of encapsulating a trustee, but the benefits are also at the cost of adding the appropriate function to the delegate's service object each time you need to add a new function to the trustee. As the features of the trustee become more and more, you will find that the things you are dealing with become
