redisConnection (Type of variable)

In french: redisConnexion

The type redisConnection makes it possible to define all the advanced characteristics of a connection to a Redis server (or cluster). The characteristics of this connection can be defined and changed using different WLanguage properties.

Remark: For more details on the declaration of this type of variable and the use of WLanguage properties, see Declaring a variable.

Example

// Connection to a server
gRedisSimple is redisConnection
gRedisSimple.Server = "myserveur:7001"
gRedisSimple.ConnectionTimeout = 1s
gRedisSimple.Password = "secret password"

// Connection to a cluster
gRedisCluster is redisConnexion
gRedisCluster.Server[1] = "RedisNode1:7001"
gRedisCluster.Server[2] = "RedisNode1:7002"
gRedisCluster.Server[3] = "RedisNode2:7001"
gRedisCluster.Server[4] = "RedisNode2:7002"

Remarks

Properties specific to redisConnection variables

The following properties can be used to handle a connection to a Redis server or cluster:

Property name	Type used	Effect

ConnectionTimeout	Duration, integer	Maximum timeout for the connection expressed in milliseconds (20 seconds by default, which means 20000 milliseconds). This property can correspond to: an integer corresponding to the number of milliseconds, a Duration variable, the duration in a readable format (e.g., '20s' ou '20000ms').
Password	Character string	Password used if a the connection to a Redis server requires authentication.
Server	Array of strings	Array of Redis servers. Ability to specify multiple Redis servers. In the case of a Redis cluster, it will be possible to connect even if a node of the Redis cluster is inaccessible. The format of the server name must be "ip:port or dnsname:port" On Linux, it is possible to use the "unix:unixdomainsocket" format to use a connection by unix domain socket.
