called in the method, no lock is held, that is, the lock is run out and released quickly . This is why it is not advocated directly with synchronized direct modification method of the most important reason. I want to get which lock, I get, run out, hurriedly release, even if a few lines of code I still need to use this lock, I will not occupy this lock for a second. This can only be said to be a good programming habit, but it can avoid lock sequence deadlocks as much as possible.Second, perform

In terms of scalability, customers' requirements become more and more, and 20, 50, or even more than 100 requirements appear on the function list. However, in general, we can shorten them to five categories and solve the scalability problem through five ways:1. Adjust query operations The optimization of queries will allow you to get the most results with the least effort. Make full use of the query functio

Scalability is a design indicator for the computing and processing capabilities of software systems. high scalability represents elasticity. In the process of system expansion and growth, the software can ensure vigorous vitality, with few changes or even the addition of hardware devices, the processing capability of the entire system can be linearly increased to achieve high throughput and low latency and

Abstract: This article focuses on how to understand the extension of Java applications and different types of extension techniques and specific techniques, and introduces some general extension strategies for Java enterprise applications.To be honest, "extensibility" is a comprehensive and detailed topic that is often not fully understood. It is generally thought that extensibility is synonymous with high availability, and I have seen programmers and architects "veteran" recommend clustering as

The scalability of the Web site is designed to allow for the ability to continuously expand and enhance the system's capabilities with minimal impact on existing systems. Here is a detailed description of the "extensibility" and "scalability" concepts that are easy to confuse: Extensibility Performance: infrastructure does not need to change frequently, applications are less dependent or coupled, and can re

We know, for a large portal site, scalability is very important, how to have good scalability in both vertical and horizontal, you need to do architectural design when the principle of a division, I want to say in a number of ways how to divide: The first is the transverse points: 1. Large Web sites to dissolve into a number of small sites: when we have a site with multiple functions, we can consider spli

Abstract: sentinel provides a variety of SPI interfaces to provide scalability. You can expand the interface implementation based on the same Sentinel-core, so that you can easily add custom logic to Sentinel. In order to unify the initialization process, the initialization logic extension mechanism abstracts some initialization logic of the initfunc interface, for example, registering a dynamic rule source (example) to register the statisticslot call

Mono 3.8.0 was released on September 10, September 4. The runtime of this version brings some performance and scalability improvements, and completes the migration to the Windows platform. Mono follows the gnome and Linux kernel version numbering policies, meaning that 3.8 is a major stable version after 3.6 (released last month. This version improves performance: JIT can better deal with the remainder operation of the long type with the power of di

business reputation and potential customer loss. Global enterprises operate across time zones to provide around-the-clock business services. The scheduled maintenance window for system maintenance and upgrade no longer exists. Distributed enterprises must be able to provide similar services in each geographic location and avoid network faults or transmission time. Reliability, availability, and scalability a solution implements some or all aspects of

. The actual requirement is to check the hardware resource utilization of this tier server. For example, CPU, memory, disk read/write, and so on. If it is very high, you must add a new server to deploy the same application of this tier to the new server. So that new servers can share some pressure. In fact, this is to enable applications to support high scalability. There is a hardware load balancing between each tier, and then it is the service inter

Here I will take two examples to fully illustrate the scalability of Java polymorphism, as a good programmer, it is necessary to understand the scalability of the program, very conducive to the development of the program follow-up.The first example: the use of computer motherboards as an example, on the computer we are familiar with the motherboard, there is not a lot of modules, network cards, sound cards,

Java concurrent programming and scalability (2)Blocking Non-competing synchronization can be fully processed in the JVM. Competing synchronization may require the intervention of the operating system to increase overhead. When the lock is in competition, the thread that fails the competition will be blocked. When implementing blocking behavior, JVM can adopt spin wait, that is, continuously trying to get the lock through the loop. Until successful. Yo

. For example, the UI Tier can be dozens of servers, hundreds of servers, or even thousands of servers. The number of servers required for each Tier is configured based on actual needs. The actual requirement is to check the hardware resource utilization of this Tier server. For example, CPU, memory, disk read/write, and so on. If it is very high, you must add a new server to deploy the same application of this Tier to the new server. So that new servers can share some pressure. In fact, this is
