+## vtctldclient OnlineDDL throttle
+
+Throttle one or all migrations.
+
+```
+vtctldclient OnlineDDL throttle <keyspace> <uuid|all>
+```
+
+When using `all`, throttling applies not only for existing migrations but also for any other future migration. It is the equivalent of running `UpdateThrottlerConfig --throttled-app=online-ddl`.
+
+Note that this command runs successfully whether the throttler is enabled or not. If the throttler is disabled, then migrations are not throttled, but the rule is still there. If the throttler is then enabled, the rule will apply.
+
+### Examples
+
+```
+OnlineDDL throttle test_keyspace 82fa54ac_e83e_11ea_96b7_f875a4d24e90
+OnlineDDL throttle test_keyspace all
+```
+
+### Options
+
+```
+  -h, --help   help for throttle
+```
+
+### Options inherited from parent commands
+
+```
+      --action_timeout duration   timeout for the total command (default 1h0m0s)
+      --server string             server to use for connection (required)

+Unthrottle one or all migrations.
+
+```
+vtctldclient OnlineDDL unthrottle <keyspace> <uuid|all>

+
+Note that if you issue a `vtctldclient OnlineDDL throttle my_keyspace all`, then throttling applies to all migrations, current and future. It is then impossible to exclude a specific migration via `vtctldclient OnlineDDL unthrottle my_keyspace 82fa54ac_e83e_11ea_96b7_f875a4d24e90`.
