1. Spring-data-redis IntroductionEncapsulates the Redis client, making it easier to use.The advantage is that the client connection is placed in a connection pool to improve performance. There is also the ability to switch between different clients without changing one line of code (a technique that spring is accustomed to).The latest version of this writing is 1.3,Currently supports the following 4 types of Java clients, which are free to switch without changing the code.

The Twitter architecture, based on public information on the Internet, is mainly in the cache aspect. It is not necessarily the same as the actual architecture because it is supplemented by the author.Some data:
The cache is divided into page cache, fragment cache, row cache, vector cache, and cache hit rate.
Fragment cache stores data in various API request formats, including XML, JSON, RSS, and atom.

Use Twitter's cursor method to paging Web data bitsCN.com
This article discusses how to implement the data paging function in Web applications. different technical implementation methods differ in performance.
For the technical implementation method of the function, take MySQL as an example.

You can read the last 20 tweets, but you do not kno
