Springboot Connect Redis and dynamically switch database As we all know, Redis has a db, in the Jedis can use the Select method to dynamically select the Redis database, but in the stringredistemplate provided by Springboot does not have this method, Fortunately, stringredistemplate reserved a setconnectionfactory met

Label: Because a large number of references are used in this connection-controlled class, setting a macro in and out is just a sign that the token is output or input.This class design is very similar to the mysqlobj design, but the difference is that there is no need for an object to store the query value specifically, because Redis is key-value, and the query returns a string or a number directly.So here w

Access to Redis, similar to access to MySQL, can be done via client software. When MySQL is installed on a server A, I can access this MySQL on the other server via Server A's Ip,mysql port number, account, password to connect to MySQL on server A. Then access to Redis is actually the same principle, Redis can be inst

is obviously not possible, a connection of multiple PHP-FPM mutual pinch will also cause bottlenecks, if it is a php-fpm a connection? Obviously this is desirable, so using a redis long connection with PHP, the Php-fpm.ini configuration is as follows: PM = Static Pm.max_children = Pm.max_requests = 10240 PHP uses pc

This article describes how to connect Python to Redis. Redis is a high-performance, memory-based database, for more information, see The python redis module used when I wrote the zabbix storm job monitoring script today. it has been useful before, but I don't know much about it, today, I read the relevant api and sourc

Today in writing Zabbix storm job monitoring script used Python Redis module, before also useful, but not too much understanding, today looked at the relevant API and source code, see the implementation of ConnectionPool, here simply say. Before ConnectionPool, if you need to connect Redis, I use Strictredis this class, in the source code can see the specific exp

request. Then I looked at the source of the Radix.v2 pool package and found that the library itself did not detect bad connections and replace them with a new connection mechanism. That is, every time I get a connection from the connection pool, there may be a bad connection. So, my temporary solution was solved by ad

Using Jedis in multithreaded situationsStrange errors occur when using the same Jedis instance in different threads. But it's not good to create too many implementations because it means there are many sokcet connections that can cause strange errors to occur. A single Jedis instance is not thread-safe. To avoid these problems, you can use Jedispool, Jedispool is a thread-safe network connection pool. You can use Jedispool to create some reliable Jedi

This problem, you will definitely encounter after using PHP Redis. Therefore, this dish in the principle of open-minded advice, but also around the internet for advice. The answers are the following two kinds:1, Redis does not actively close.After the discovery, this answer is purely baseless assertion, nonsense.2, configure the/etc/sysctl.conf, change the following configuration:Net.ipv4.tcp_syncookies = 1
