Set or update one or more JSON values according to the specified key-path-value triplets
JSON.MSET is atomic, hence, all given additions or updates are either applied or not. It is not possible for clients to see that some of the keys were updated while others are unchanged.
A JSON value is a hierarchical structure. If you change a value in a specific path - nested values are affected.
key
is key to modify.
path
is JSONPath to specify. For new Redis keys the path must be the root. For existing keys, when the entire path exists, the value that it contains is replaced with the json value. For existing keys, when the path exists, except for the last element, a new child is added with the json value.
value
is value to set at the specified path
JSET.MSET returns a simple string reply: OK if executed correctly or error if fails to set the new values
For more information about replies, see Redis serialization protocol specification.
