Introduced Applications typically use data caching to improve performance, especially for applications that are heavily used for read-only transactions. These applications update the database directly when the data is changed. The problem is that as the load increases, response times are extended as the updates grow. Databases are not good at performing concurrent transactions that handle a large amount of records. In contrast, processing bulk transactions is the strength of the database. In f

Unity3d How to reduce the size of the package to the extreme, the picture is the most space in the game app resources, so please do not understand u3d to the picture file storage way to understand, see "unity3d-texture image Space and memory consumption analysis." Because U3d does not elaborate on the compression of resources, many projects have a headache when they encounter packet size bottlenecks. I am not immortal, also painful, but experience a f

New Year's Day holiday received a call from Ali Wu, was told that MySQL checked to the extreme SQL optimization: 1 million raw data, of which 500,000 repeats, the deduplication of the 500,000 data written to the target table only 9 seconds. This is a staggering number, and it will take some time to know that only the insert 500,000 records. Then came the interest, his own experiment, thinking, summed up to do it.I.

weights. Only in this way can we surpass our competitors. Because you are after all, others themselves in other areas have accumulated a lot of weight. To go beyond, of course, you can do more. I have thought of such a way before, we can refer to. But not recommended, it is best to use the way I said above. My approach is this, if my site has three core keywords, in order to assign the site link to the extreme. Then I will have a keyword first to do

So four procedure calls are executed in parallel.Figure Six(5) View event execution logSELECT * from T_event_history;The results of query 7 show.Figure SevenAs you can see, each procedure executes for 3.5 seconds, and because it is executed in parallel, the total execution is also 3.5 seconds, and the optimization effect is almost the same as the shell daemon process.Reference:Increasing slow query performance with t

What is extreme programming? 　　 Extreme Programming is a development discipline with simplicity, communication, feedback, and courage as its basic purpose. The practice is to closely associate the entire team with effective practice rules, and enable the team to know their current situation and adjust the rules at any time through full feedback to adapt to their special circumstances.

The core of extreme programming is four: communication, simplicity, feedback, and courage. These four principles are also noticed during the project process, but the two masters Kent Beck and Martin Fowler can combine these four points, so that they can make up the extreme programming of the carriage, but it is not small to create. Next, I will only talk about some of my understanding of these four core iss

Extreme Psychology Reason: An emotional manifestation of extreme psychology people stick to their own opinions when they are aware of problems. When you look at things, you always judge things based on your own experience, stick to your own inherent ideas, and reject others' opinions. This will b

Extreme Programming (XP) was proposed by Kent Beck in 1996. When Kent Beck worked with Ward cunnheim in the early 1990s s, he had been exploring new software development methods to make software development easier and more effective. Kent carefully observed and analyzed the prerequisites, possible actions, and difficulties for simplifying software development. In March 1996, Kent finally introduced a new idea of software development-XP in a project fo
