redisHSet: Store a hash value in Redis.

In rredis: "Redis" Key/Value Database Client

Description

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

Usage

redisHSet(key, field, value, NX = FALSE)

Arguments

key	The (required) character identifier for the key name.
field	The (required) character identifier for the field name.
value	The (required) object to associate with the key/field.
NX	If NX = TRUE, existing values will not be replaced.

Details

Redis hash values store values in one or more fields associated with a single key name.

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

TRUE is returned on success. If NX = FALSE and a value already exists, the value will not be replaced and FALSE will be returned.
