JP Robinson, principal engineer at the New York Times, had "drunk Peter's Koolaid" with respect to Go kit.
Github.com/nytimes/gizmo adapts Go kit for use inside a production ecosystem with a bunch of existing legacy services. The NYTimes uses it across almost all their production Go services.

Publisher/subscriber Subscription-Release modeThe follow-up will continue to collate some of these years to do some of the pre-research demo, and some of the leading-edge technology, with everyone to study technology and common progress.There are many ways to implement a publish subscription, the following is mainly about the publication of the subscription in WCF, the main reference book "Programming WCF Services", gossip not much to get to the point
The first part is quoted in: Click to open1: Brief IntroductionPub-sub mode is not generally processed by the system's key data. The Publisher does not care if the Subscriber receives the published message, nor does the subscriber know if he or she has received all the messages from the publisher. You also don't know when subscribers start receiving messages. Similar to broadcasting, radio. So logically, it
During transactional replication, there are times when data between the Publisher and Subscriber is inconsistent for a variety of reasons, often due to one of several reasons:
An agent ran an error or the agent process crashed
A larger publication uses backup restores instead of snapshot replication initialization, and the data is modified by the publisher after the backup
Non-Distribution Agent thread modifies subscriber's data

Label:Recently encountered "the line was not found at the Subscriber when applying the replicated command" problem, the error is as follows: The official advice is to resynchronize and initialize the subscription, which, of course, is an option, but for hundreds of grams of production libraries, this approach consumes a lot of resources and time. You can fix the error data by locating the error data, selecting Skip, and so on after the main library i
The previous article in this series provides an overview of how Ibm®websphere®service Registry and Repository and IBM WebSphere Process Server are used for service consumption governance. This article describes some implementation details to show you how to customize the WebSphere service Registry and Repository to support service consumption governance, how to implement the Subscriber authorization process using WebSphere process Server, and how to u
Everyone, including myself, knows how important it is to have a high-quality subscriber list for the product. The subscriber list is a long and difficult process.
When someone subscribes to your email, they give you valuable trust. Your subscriber allows you to appear in their personal space (inbox) in return, you cannot abuse your new rights.

From the transaction code smw01, we can see that a BDOC may be sent to more than one target site. For example, the five sites shown in the transaction code will receive the site, the highlighted smof_erpsite indicates that client 504 of ERP system qi3 receives the BDOC.So where is the site in the list read from?Take bdocproduct_mat as an example to maintain the callback function in the smw3fdbdoc View:The first callback smoh_replication_wrapper_msg is responsible for deciding the sites from whic

Publish-Subscriber design modeDefinedDefines a one-to-many dependency between objects, and all objects that depend on it will be notified when the state of an object changesThe difference between the observer pattern and the publish subscription patternThe Observer pattern is scheduled by a specific target (publisher/observer), and the Publish/subscribe pattern is dispatched by a separate dispatch center, so there is a dependency between the
Observer mode (also known as publisher-Subscriber mode) should be one of the most common patterns. are used in a lot of languages. Including the DOM events we normally touch. It is also an observer pattern implemented between JS and Dom.

Just subscribe to the div click event. When you click on the div, the function click is triggered.
