```
Clears all keys from an Active-Active database.

```sh
crdb-cli crdb flush --crdb-guid <guid>
         [ --no-wait ]
```

This command is irreversible. If the data in your database is important, back it up before you flush the database.

Run flush from only one participating cluster. The flush operation propagates to all other clusters automatically.

### Parameters

| Parameter           | Value  | Description                         |
|---------------------|--------|-------------------------------------|
| crdb-guid  | string | The GUID of the database (required) |
| no-wait             |        | Does not wait for the task to complete |

### Returns

Returns the task ID of the task clearing the database.

If `--no-wait` is specified, the command exits. Otherwise, it will wait for the database to be cleared and return `finished`.

### Example

```sh
$ crdb-cli crdb flush --crdb-guid d84f6fe4-5bb7-49d2-a188-8900e09c6f66
