Cuando creaste un flujo, lo hiciste y lo iniciaste inmediatamente, o bien lo creaste sin iniciarlo.
Si has creado la emisión, pero no la has iniciado, puedes hacerlo ahora. Al iniciar el flujo, Datastream puede transferir datos, esquemas y tablas de la base de datos de origen al destino.
Ve a la página Streams (Streams) de la Google Cloud consola.
Marca la casilla situada a la izquierda de la emisión que quieras iniciar.
Haz clic en EMPEZAR.
En el cuadro de diálogo, haz clic en INICIAR. El estado de la emisión cambia de Not started a Starting y, después, a Running.
Después de iniciar una transmisión, puede monitorizarla
para verificar que Datastream ha transferido datos de la base de datos de origen al destino.
Pausar la emisión
Después de iniciar una emisión, puedes pausarla. Cuando se pausa un flujo, Datastream no extrae datos nuevos de la base de datos de origen al destino. Sin embargo, es posible que se sigan escribiendo algunos datos en el destino mientras sigan fluyendo los datos "en tránsito".
En algunos casos, si pausas una emisión, la base de datos de origen debe conservar los datos hasta que reanudes la emisión. El periodo de conservación de la base de datos de origen puede ser limitado. Si la emisión se pausa durante un periodo superior al de conservación de la fuente y, a continuación, se reanuda, puede que la emisión falle. Si esto ocurre, elimine el flujo, cree uno nuevo y, a continuación, inícielo para que Datastream pueda transferir datos, esquemas y tablas de la base de datos de origen al destino.
Ve a la página Streams (Streams) de la Google Cloud consola.
Marca la casilla situada a la izquierda del flujo que quieras pausar.
Haz clic en PAUSAR.
En el cuadro de diálogo, haz clic en PAUSAR. El estado de la emisión cambia de Running a Draining. El drenaje de un flujo es el proceso de vaciar el flujo para que no contenga ningún dato.
Una vez que se hayan enviado todos los datos de la secuencia, su estado cambiará de Draining a Paused.
Después de pausar un flujo, puedes reanudarlo para que Datastream pueda transferir datos nuevos de la base de datos de origen a la de destino.
Reanudar la emisión
Puedes reanudar una emisión que hayas pausado. Al reanudar la
transmisión, Datastream puede transferir datos nuevos de la base de datos de origen al
destino.

The actions include:\n\n- [Starting a stream](#startastream)\n- [Pausing a stream](#pauseastream)\n- [Resuming a stream](#resumeastream)\n\nStart the stream\n----------------\n\nWhen you [created a stream](/datastream/docs/create-a-stream#createthestream), you either created the stream and started it immediately, or created the stream without starting it.\n\nIf you created the stream, but you didn't start it, then you can do so now. By starting the stream, Datastream can transfer data, schemas, and tables from the source database to the destination.\n\n1. Go to the **Streams** page in the Google Cloud Console.\n\n [Go to the Streams page](https://console.cloud.google.com/datastream/streams)\n2. Select the checkbox to the left of the stream that you want to start.\n\n3. Click **START**.\n\n4. In the dialog, click **START** . The status of the stream changes from `Not started` to `Starting` to `Running`.\n\n | It takes about 30 seconds for the stream to start running. Background resources need to start so that the stream can start.\n |\n | For more information about the states and transitions of a stream, see [Stream lifecycle](/datastream/docs/stream-states-and-actions).\n\nAfter starting a stream, you can [monitor it](/datastream/docs/monitor-a-stream)\nto verify that Datastream transferred data from the source database to\nthe destination.\n\nPause the stream\n----------------\n\nAfter [starting a stream](#startastream), you can pause it. When a stream is\npaused, Datastream doesn't pull any new data from the source database\ninto the destination. However, some data may continue to be written to the\ndestination as data \"in flight\" continues to flow.\n\nIn some cases, if you pause a stream, then the source database must retain the\ndata until you [resume the stream](#resumeastream). The retention period for the\nsource database may be limited. If the stream is paused for longer than the\nsource retention period, and then the stream is resumed, this can cause the\nstream to fail. If this occurs, [delete the\nstream](/datastream/docs/delete-a-stream), [create a new\none](/datastream/docs/create-a-stream), and then start it so that\nDatastream can transfer data, schemas, and tables from the source\ndatabase to the destination.\n\n1. Go to the **Streams** page in the Google Cloud Console.\n\n [Go to the Streams page](https://console.cloud.google.com/datastream/streams)\n2. Select the checkbox to the left of the stream that you want to pause.\n\n3. Click **PAUSE**.\n\n4. In the dialog, click **PAUSE** . The status of the stream changes from `Running` to `Draining`. Draining a stream is the process of emptying the stream so that it doesn't contain any data.\n\n After the stream is drained of all data, then the status of the stream changes from `Draining` to `Paused`.\n | For more information about the states and transitions of a stream, see [Stream lifecycle](/datastream/docs/stream-states-and-actions).\n\nAfter pausing a stream, you can [resume it](#resumeastream) so that\nDatastream can transfer new data from the source database to the\ndestination.\n\nResume the stream\n-----------------\n\nYou can resume a stream that you [paused](#pauseastream). By resuming the\nstream, Datastream can transfer new data from the source database to\nthe destination.\n\n1. Go to the **Streams** page in the Google Cloud Console.\n\n [Go to the Streams page](https://console.cloud.google.com/datastream/streams)\n2. Select the checkbox to the left of the stream that you want to resume.\n\n3. Click **RESUME** . The status of the stream changes from `Paused` to `Running`.\n\n | For more information about the states and transitions of a stream, see [Stream lifecycle](/datastream/docs/stream-states-and-actions).\n\nAfter resuming a stream, you can [monitor it](/datastream/docs/monitor-a-stream)\nto verify that Datastream transferred new data from the source database\nto the destination.\n\nWhat's next\n-----------\n\n- To learn more about streams, see [Stream lifecycle](/datastream/docs/stream-states-and-actions).\n- To learn how to modify your streams, see [Modify a stream](/datastream/docs/modify-a-stream).\n- To learn how to recover a stream, see [Recover a stream](/datastream/docs/recover-a-stream).\n- To learn how to delete an existing stream, see [Delete a stream](/datastream/docs/delete-a-stream)."]]
