Redis: is a high-performance Key-value database.Simply put: When you use a relational database, files, or other media to store things, performance is slow to respond slowly, this time you need to take something to cache. There are several kinds of similar products, at present more popular, in our business is this. At present, this thing in the cluster state, for our millions concurrency to provide good support.Today, let's talk a little bit about how
,master and slave that are used to save the results of the job share this channel,master subscribe to this CHANNEL to get job run results. Each slave is responsible for publishing the results of the job execution to this channel.

Redis's list type has a good feature, that is, the length of the current list will be returned after each element is added. With this feature, we can monitor its length, for example, our key is the IP address registered by the user, and the list stores the ID of the user already registered on this IP address. When the number of users exceeds 1000, an alarm is triggered, the subscription and release functions of redis help you easily implement the Noti
