The new version mainly realizes the function of cluster, and then automatically migrates the data after adding or deleting the cluster nodes. The core of enabling Redis cluster online reconfiguration is the ability to move slots from one node to another.

These days, take over a colleague's code, about the development of micro-letter interface, that a heap of if, see Brother egg pain, this problem is also a lot of beginners easy to make, so specially to write this refactoring. Let's take a look at the problem with this code, if the code block logic in the if else inside is hard to change, making it reusable 0 and difficult to read. Of course, if there are only one or two, or 3, this is not a very good

Excerpt: Some Ideas about large-scale software refactoring The reconstruction discussed here is"Implement a functionWhileDedicatedOngoingLarge Scale".How far can you see the architecture design? Simply put, what we need to do is to completely separate the UI code of a software from the core functions, and then make the core part into a separate product. Of course, everyone understands the principle of separation between the presentation layer and the

You've been trying to refactor a very old module, but it's disgusting if you just look at it. Documents, strange functions and names of classes, and so on, the whole module is like a ragged man with fetters, though able to walk, but it is already uncomfortable for people. In the face of this situation, the real programmers will not concede, they will accept the challenge of serious analysis, it is not afraid of rewriting. Eventually the module will be refactored, just as it did with the amazing

GUI, use the self encapsulate Field. Compile, test. Call the Set function in the event handler to update the GUI directly. Put a value function in the event handler and use it to update the GUI component to the current value of the model, which is of course not necessary, because you just set it yourself with its value. But using the SetPoint function in this way allows any of these actions to be executed later, which is the point of this step. When making this change, do not use the ac

We know that "easy to understand and be used interface" is the key to develop

JDK 5.0 has made significant grammatical improvements, although the source code developed in the lower version of the JDK can run directly into JDK 5.0 without any modification. However, there is a need for a version upgrade refactoring, so you can apply JDK 5.0 for and while loops, automatic loading/unpacking, generics, and other improvements to make the code more compact while the code performance is optimized. So JBuilder's program, specifically fo
