All synchronized data tables use primary keys as much as possible, and if there is no primary key, SQL Server p

suffer a lot, but always have the beginning!The above can be skipped directly First of all, I have a personal understanding of the Observer pattern: The Observer pattern, also known as the Publish-subscribe (publish/subscribe) mode, is clearly a function of two different objects, such as RSS. It is a publisher (post some high-level answers to some questions), I am a subscriber (I subscribe to the relevant post in my mailbox), my colleagues and

, it cannot assume that other objects are who. In other words, you don't want these objects to be tightly coupled.Example Analysis Scene Newspapers, magazines subscriptions: 1. The newspaper's business is to publish the newspaper 2. Subscribe a newspaper to a newspaper, and if they have a new newspaper, they will send it to you. As long as you are their subscriber, you will always receive the new newspaper 3. When you don't want to read

1. IntroductionBasic knowledgeThe basic component of the responsive code is observables and subscribers (in fact Observer is the smallest building block, but the most used in practice is subscriber, because Subscriber is the counterpart of Observables. ）。Observable sends messages, while Subscriber is used to consume messages. The message is sent in a fixed mode.

, and the broker goes down before the broker sends the message to Subscriber, and if the broker restarts after a durable transfer, The message is read from disk and passed to subscriber, and if non-persistent transmission is used, the message is lost.For official documentation of transfer modes, refer toThe difference between message durability and message persistence: I saw it in "ActiveMQ in action" and u

can be divided into two types of wired access and wireless access, access to the user's environment and needs, it can be broadly divided into home access, campusAccess, institutions and enterprise access.From the perspective of implementation technology, the current broadband access technology is mainly the following: Digital subscriber line xDSL, optical fiber coaxial cable mixed network HFC technology, optical fiberAccess technology, wireless acces

: Defined in the Protocol,HubServer: 1. Send a verify subscriber request, requesting the subscriber to return the 200 status code and the challenge code. 2. Push the updated data of the subscribed Google Reader shareds items to the subscriber. 3. Send an expiration request to determine whether to continue renewal. Ask the

In reality, not all requests are waiting for a response, but they are not waiting for a response. So compared with the REQ-REP, PUB-SUB mode is much easier to understand. Have you heard of broadcast? Have you used the radio? That's what it means. Publish-subscribe Pattern: Publish and subscribe mode. In reality, not all requests are waiting for a response, but they are not waiting for a response. So compared with the REQ-REP, PUB-SUB mode is much easier to understand. Have you heard of broadcast

I. Release and subscription mechanismsWhen a client sends a message to a subscriber via the PUBLISH command, we call the client Publisher.When a client uses the SUBSCRIBE or Psubscribe command to receive information, we call the client the Subscriber (Subscriber).To understand the relationship between a decoupled publisher (publisher) and a

Basic Concepts The observer (observer) mode is widely used in client Javascript programming. All browser events are in this mode. It is also called a custom Event (custom events). Compared with events triggered by browsers, custom events represent events that are programmed by you. In addition, another alias for this mode is also called the subscriber/publisher mode. The main motivation behind the design is to promote loose coupling. In this mode, not

Original: Reproduced please indicate the sourceReactivecocoa/rxswiftThe Native app has a large part of the time waiting for events to occur and then responds to events such as 1. Wait for the network request to complete,2. Wait for the user's Operation ,3. Wait for certain status values to change , etc.Wait until these events have occurred, and then do further processing.But these waits and responses do not have a unified approach. Delegate, Notification, Block, KVO, often do not know which is t

Rxjava's GitHub homepage, the deployment part has nothing to say ~Https://github.com/ReactiveX/RxJava BasisThe two core Rxjava are observables (observed, event source) and Subscribers (Observer). Observables emits a series of events subscribers handle these events. The event here can be anything you are interested in (touch events, web interface calls return data ...). ） A observable can emit 0 or more events, knowing the end or error. Each event is emitted, its

Engine (including SQL Server Replication), Management Tools. Second, the primary database server (publisher) configuration: 1. Create a new sample database on the primary database server CNBlogsDB1 Cnblogsdemo (note that recovery mode will use the default value full, only this mode can be replicated), and then create a test table, such as: Cnblogstest. 2. Set the folder where snapshots are stored: Before creating a publication, set up the folder where the snapshot is held, and the snapsho

Rxjava is just a Java implementation of Reactivex (reactive Extensions), Reactivex is a responsive extension framework with many implementations, such as Rxandroid, RXJS, Rxswift, Rxruby, and so on. Rx uses a form similar to the observer to achieve a variety of functions, with our general writing code thinking of a greater difference. Initial contact may be difficult to understand, but once you have mastered it, you will feel the strength of it. The principle is to create a observable object to
