Best Application Scenario: Suitable for scenarios where you want to use databases similar to Cassandra (similar to Dynamo) but cannot handle bloat and complexity. It is applicable to scenarios where you plan to replicate multiple sites, but you need to have requirements on the scalability, availability, and error handling of a single site.
For example, sales data collection, Hong Kong virtual hosts, factory control systems, strict downtime requirements, can

Now let's pause for a moment and change the subject.
At the end of 2010, when I was working at Zynga, I had a bit of time to go back to using PHP from Python. So I took a little time to read something. Among the books I have read, there is a book in which some of the discussions describe the concept of "Data Flow Programming" (Dataflow programming) and "declarative Concurrency

Game Engine Based on Cocos2d-x APIs. It is currently rendered using canvas and will support WebGL in the future. It is led by the core team of domestic Cocos2d-x development and maintenance, industry leaders, HTML5 promoter Google to provide support for this project. At the same time, Zynga, Google and other large companies are also involved in its design work.
