preface When I am running a deep learning or neural network model training, we often need to run many epoch s. Of course, we are most concerned about the accuracy of the model and other parameters in the training, but before that, we need to go through a parameter adjustment process. The parameter adjustment process is often determined a ...

Setting redis master-slave is mainly used to edit configuration files on different hosts We have three main engines ready server1, server2 and server3 respectively The master-slave automatic switching of redis is based on sentinel 1.

Kill will be forced at this timeDrop the task and restart it, but every time you need to log in to the ...

Persistence Redis supports two persistence mechanisms: RDB(Redis DataBase) and AOF(Append Only File). The persistence function effectively avoids the problem of data loss caused by process exit. Data recovery can be realized by using the previously persistent file when restarting next time. (redis data is stored in memory. In case of sudden do ...

In the previous articles, we basically described the implementation and source code analysis of spring security login authentication and authorization authentication.

1, Preface: In the era of big data, the concurrency of network requests leads to huge database I/O overhead. Therefore, in order to alleviate the pressure of the database, caching technology is essential. Among them, redis is basically one of the server's caching services. Although caching technology is very easy to use, there will be a variet ...

person one is in love with Recently, I met such a demand in the company's development: how to realize regular order? And you can interrupt, restart and delete this task at any time. I thought of the following technologies at that time @Scheduling annotation + Cron expression. Hahahahahaha, maybe many small partners will do the same, but later ...

Redis profile INCLUDES redis can load multiple configuration files Application scenario: When you have multiple redis servers, you can select a public redis configuration file and set some differentiated configurations on each redis server, which can be realized by using include in the configuration file ########################## ...
