EXEC

{{< 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 >}}

Executes all previously queued commands in a transaction and restores the connection state to normal.

When using [WATCH]({{< relref "/commands/watch" >}}), EXEC will execute commands only if the watched keys were not modified, allowing for a check-and-set mechanism.
