redisSet

Store a value in Redis.


Description

Store a value identified by a character key name in the Redis database. Any existing value with the same key will be replaced by the new value unless NX is set to TRUE.

Usage

redisSet(key, value, NX = FALSE)

Arguments

key

The (required) character identifier for the value to be stored.

value

The (required) object to associate with the key.

NX

If NX = TRUE, existing values will not be replaced.

Details

The value is copied to the Redis server. The value to be stored can be any serializable R object up to the Redis maximum object size (excluding, for example, external pointer references). References to other R objects or environments inside the value are not guaranteed to be preserved.

In order to store strings that can easily be read by other clients, first convert the character object using the charToRaw function as shown in the examples.

Value

The value “OK” is returned upon success (conforming to the usual Redis behavior).
