so on.You can also use a negative subscript, which means 1 for the last member, 2 for the penultimate member, and so on.An out-of-range subscript does not cause an error.For example, when the value of start is larger than the maximum subscript for an ordered set, or Start > Stop, the Zrange command simply returns an empty list.On the other hand, if the value of the stop parameter is larger than the maximum subscript for an ordered set,

Example of redis queue operation (php ). The code for copying data to the queue is as follows :? Php $ redisnewRedis (); $ redis-connect (127.0.0.1, 6379); while (True) {try {$ valuevalue _. date (Y-m-dH: I: s); $ redis-LPUSH (key1, $ v join operations The code is as follows: $

$redis = new Redis ();$redis->connect (' 127.0.0.1 ', 6379);echo "Connection to server sucessfully";Store data in Redis list$redis->lpush ("Tutorial-list", "Redis");$redis->lpush ("Tuto

different application deployment, and only one database server, this concurrency problem is easily solved. So now let's take a look at whether to move it to the application to avoid adding database servers to the business.For example, there are two application servers and one database server. The idea is to deploy Redis on the database server. When the two servers operate on the concurrent cache or queue,

queue and the cache, and will not cause any troubles in the concurrent environment, because all operations in Redis are atomic operations.As for comment on the two, the good or the bad will be free, the existence is the reason, the best choice is the best.Let's start to play with the queue (distributed) design YY in Redis. Please give me some advice.Scenario:Currently, all projects are deployed on multiple

There are ways to mitigate even this problem by building multiple Redis instances that are implemented through multiple redis connections. 3. In addition, a single large Redis instance can also increase the diffic
