Number", "Virtual node" in the hash The space is arranged in hash value. as an example of the above only deployed NODE1 and NODE3 (NODE2 deleted diagram), the previous objects are unevenly distributed on the machine, now we take 2 copies (copy number) as an example, so that there are 4 virtual nodes in the entire hash ring, and the graph of the final object mapping is as follows: based on the known object mapping relationship: Object1->node1-1,object2->node1-2,object3->node3-2,object4->node3-1.

Requirejs will have a good help with all these concerns.This is what we are going to talk about in the next chapter of the question of dependency.Here by the way give the students a brief description of the AMD and CMD overview and differencesAMD: is the abbreviation for "Asynchronous module definition", meaning "async module definition".

the previous (detailed) operation steps, but the "data" effect is the same.The AOF approach also poses another problem. Persistent files can become more and more large. For example, we call the INCR Test command 100 times, the file must save all 100 commands, in fact, 99 are redundant. Because you want to restore the state of the database, it is enough to save a set test 100 in the file. In order to compress the aof persistence file. Redis provides the bgrewriteaof command.

Here are some of
