We all know that the browser will cache the webpage that has accessed the website. The browser accesses a webpage through the URL address, and the webpage content will be cached on the computer while displaying the webpage content. If the webpage is not updated, when the browser accesses the URL again, the webpage will not be downloaded again, but the locally cached webpage will be directly used. The web page will be downloaded again only when the website clearly identifies that the resource has
What is RSS?RSS is a simple way for websites to share content with other sites (also called aggregate content). It is usually used for news and other websites in order, such as blogs. A project may contain all the news. Or, it's just additional content or a brief introduction. Links to these projects can usually be linked to all content. Network users can read the content of the website that supports RSS output without opening the website content page by using RSS-supported news aggregation soft
article, I would like to devote some space to the consumer group, at least to say what I understand. It is worth mentioning that since we are basically only discussing consumer group today, we do not have much discussion about individual consumers.What is consumer group? Word, consumer group is a scalable and fault-tolerant consumer mechanism provided by Kafka. Since it is a group, there must be multiple consumer or consumer instances within the group (consumer instance), which share a common I

Currently, RSS readers can be classified into three types.
First, most readers are applications running on the desktop of computers.ProgramThe news title of the subscribed website can be updated automatically and periodically. Among these readers, awasu, feeddemon, and rssreader are available in free trial and paid pro versions. Recently, several RSS readers have been released in China: Zhou botong, watching the world and reading blogs. In addition,

I deleted the code and deleted the unimportant part. In general, ConsumerInfoManager also needs a Cache, which is used to store all entity classes, and the queue is part of the Cache, generally, when a task in the queue expires, You need to delete or retrieve it from the Cache to perform some operations.
Of course,
in this partition, but it may also be the follower of another partition .)
7. Producer
The producer is responsible for specifying the topic to which the record is published.
8. Consumers
8.1 consumers use consumer group names to mark themselves. Each consumer group is a logical subscriber of topics.
8.2 each record published to topics will be delivered to a consumer instance in each consumer group subscribed.
8.3 Each consumer group consists of multi
Js observer mode publishing/subscriptionIn the past, when writing pages, there were never so many asynchronous operations. I only learned about asynchronous programming when using 'setinterval' and 'xmlhttprequest. In the course of learning node this time, it is clear that asynchronous failback is used. But when coding and writing code, it falls into the callback hell ). Es6Promise is used to solve some problems. We also see the event-driven solution of the EventProxy module. In the process of u
