postgresql scalability

two examples show us that high performance is doing as many things as possible in a short window of time. This is, of course, the most classic explanation for the term performance. But at the same time, using threads can also be a good way to improve the response speed of our programs. Imagine that we have such a graphical interface of the application, there is an input box above, the input box under the name is called "Processing" button. When the user presses the button, the application needs

Although application developers can best control the amount of memory required for the application, managers can significantly affect the amount of memory usage by adjusting the session time-out period.

1 Some problems of restricting BGP expansibility BGP is the IP network Interconnection protocol applied to Internet, which provides a stable and secure routing protocol for the interconnection between operators, and has rich routing control mechanism. To better control the routing strategy, most operators now deploy BGP to backbone routers. With the continuous expansion of the network, the increasing number of routers and the proliferation of routing information items, it is becoming more and m

This article explains how to use the search for left join, CROSS join, and identity values to improve the performance or scalability of a SQL Server based application. The phenomenon you will encounter: SQL queries in your application do not respond the way you want. It either doesn't return data, or it takes a surprisingly long time. If it lowers the speed of an enterprise application, the user must wait a long time. Users want the application to re

This article describes the two options for extending the database system outward to achieve higher scalability: horizontal data partitioning and vertical data partitioning. When I mention scaling out the database system, I'm actually just talking about splitting or dividing the database system so that you can use those parts and assign them to a separate database server. This allows you to spread the processing power across many servers to accommodat

production centers, website management centers, and other departments. In terms of transmission speed, most modern desktop switches provide multiple ports with 10/100 Mbps adaptive capability. 2. Work Group switches are often used as expansion devices. Most work group switches are directly considered when table switches cannot meet their requirements. Although the workgroup switch only has a small number of ports, it supports a large number of MAC addresses and has good

IETF is setting up a new working group to solve the scalability problem in the Internet routing system. This problem is caused by the Division of network traffic between various operators. The Working Group will be built on a proposal from the Cisco engineer team to build a new tunneling mechanism for Internet edge and core routers. This new approach, known as LISP (locator/separator protocol), aims to reduce the number of route table entries stored i

Oracle recently released the latest MySQL 5.7 branch Development Milestone version (DMR version)-MySQL 5.7.2. This version provides faster connection speeds, higher transaction throughput, higher replication speeds, and memory instruments and other enhancements to achieve higher performance and enhanced manageability.1. performance and scalability enhancements MySQL 5.7.2 DMR provides: 1. In the Sysbench test for InnoDB read-only queries, the speed ca

You can then notify the old master process and its working process to exit perfectly.In controlling Nginx, the whole process is described in more detail.ConclusionNginx's internal chart highly outlines how Nginx works, but behind this simple explanation is more than 10 years of innovation and optimization. These innovations and optimizations enable Nginx to perform well on a variety of hardware, while also provi

ASM-scalability and limits [ID 370921.1] ASM imposes the following limits: (1) 63 disk groups in a storage system(2) 10,000 ASM disks in a storage system(3) 2 terabyte maximum storage for each ASM disk (the bug 6453944 allowed larger sizes, but that led to problems, see note 736891.1 "ORA-15196 with ASM disks larger than 2 TB ")(4) 40 exabyte maximum storage for each Storage System(5) 1 million files for each disk group(6) 2.4 terabyte maximum

When it comes to extension, we all know that the application of some oo feature and principles can achieve this kind of effect (encapsulation), which can make the object most likely to encapsulate the changed part in the object, reduce the impact. coding to interface instead of implementation can be loosely coupled between objects for convenient extension. guideline such as OCP and SRP is also a method to achieve easy scalability. In actual applicatio

During work, we often need to develop windows Services. Therefore, a windows program with good maintainability and high scalability can save us a lot of time and effort. Let's analyze it. A windows service is regarded as an object and has the following basic behaviors: Action: Execute the action. (what does this service do) The same behavior, different implementation logic, a typical factory model. Next, we will define two windows Service Classes

APR and tomcat-native provide better scalability, performance, and integration to local server technologies. If the APR technology is not available, the following prompt is displayed when Tomcat is started: Information: The APR based Apache Tomcat native library which allows optimal performance in production environments was not found on the java. library. path:/usr/Java/jdk1.6.0 _ 06/JRE/lib/i386/client:/usr/Java/jdk1.6.0 _ 06/JRE/lib/i386: /usr/Ja

Architecture and design for performance and scalability review Deployment and Architecture Use distributed architectures appropriately. Do not introduce distribution unnecessarily. Proper use of distributed architecture, do not use distributed when unnecessary: this is not easy to grasp, mainly by experience, or to tell some specific examples of people easier to understand. Carefully select appropriate distributed communication mechanisms. Carefu
