{{< 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][tt] and restores the
connection state to normal.

[tt]: /develop/interact/transactions

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][ttc].
