complexity: O(K*(M+N)) where k is the number of keys in the command, when path is
  evaluated to a single value where M is the size of the original value (if it exists)
  and N is the size of the new value, or O(K*(M+N)) when path is evaluated to multiple
  values where M is the size of the key and N is the size of the new value * the number
  of original values in the key

{{< note >}}
This command's behavior varies in clustered Redis environments. See the [multi-key operations]({{< relref "/develop/using-commands/multi-key-operations" >}}) page for more information.
{{< /note >}}


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.

{{% warning %}}
When cluster mode is enabled, all specified keys must reside on the same [hash slot](https://redis.io/docs/latest/operate/oss_and_stack/reference/cluster-spec/#key-distribution-model).

[Examples](#examples)

## Required arguments

<details open><summary><code>key</code></summary>

is key to modify.
</details>

<details open><summary><code>path</code></summary>

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.

</details>

<details open><summary><code>value</code></summary>

is value to set at the specified path
</details>

## Examples

<details open>
<summary><b>Add a new values in multiple keys</b></summary>
