Consolidated write-backIntroduction to merge write operationsMerge write operationsSet a merge write-back systemManage rewritesMonitoring and adjustment of merge write operationsSummaryThe difference between the merge and transaction types is that the merge type can be operated by multiple parties. Merge write operations allow both the publisher and subscriber to update the release set. Although transactional rewrites allow subscribers to update t

Partitionpartition: used to scan data specified by partition in the queue; ? Combinedpartitiontions: used to scan several specified partitions in the queue. (2) After obtaining the consumer, you can call the next method of consumer cyclically to retrieve the message data until no data is returned. This scan ends. After the scan is complete, the user should take th

Google-Guava-EventBus source code explanation, guavaeventbus Guava is a Java basic class library open-source by Google. It is widely used within Google. Guava provides many functional modules, such as collections, concurrent libraries, and caches. EventBus is one of the modules. This article uses the EventBus source code to discuss its design and implementation.Summary First, let's preview all the class diagrams of the EventBus module: There are not many classes and there are almost no inherita

EventBus for Android Development Series CommunicationOverview and Basic Concepts ** EventBus ** is an Android-optimized publish/subscribe message bus that simplifies communication between components in the application and between components and background threads. For example, if you request a network and notify the UI through Handler or Broadcast when the network returns, the two Fragment must communicate with each other through Listener. These requirements can be implemented through ** EventBu

readable is a problem. In Android, there is also an open-source library EventBus with similar functions, which can help us easily implement the observer mode and reduce the coupling between components. About EventBus to explain the article, a lot of network industry, here we recommend an article, to explain the more detailed blog, http://www.cnblogs.com/angeldevil/p/3715934.html to EventBus understanding, it is best to start from the demo, first easy after hard.

The publishsubscribe function of apsaradb for redis is similar to the traditional message routing function. The publisher publishes messages, the subscriber receives messages, and the bridge between the subscriber and the subscriber is the channel or pattern subscribed. The publisher publishes messages to the specified publish or pattern, and the

, it onError() is triggered, the queue is automatically terminated, and no more events are allowed to be emitted. In a correctly-run sequence of events, onCompleted() and onError() there is only one, and is the last in the sequence of events. It is important to note that the onCompleted() onError() two are also mutually exclusive, that is, one is called in the queue, and the other should not be called again. RxJava's observer pattern is roughly as follows:2. Basic implementationBased on

Hot vs Cold observables Understanding the nature of hot and cold observables are a crucial part to master observables. Before we try to explore the topic through some practical examples, let's read through the definition from the RxJS projec T itself Cold observables start running upon subscription, i.e., the observable sequence only starts pushing values to the Observer s when the Subscribe is called. (...) This was different from hot observables such as mouse move events or the stock tickers
