Saat membuat aliran data, Anda dapat membuat aliran data dan memulainya segera, atau membuat aliran data tanpa memulainya.
Jika Anda membuat streaming, tetapi tidak memulainya, Anda dapat melakukannya sekarang. Dengan memulai aliran data, Datastream dapat mentransfer data, skema, dan tabel dari database sumber ke tujuan.
Centang kotak di sebelah kiri streaming yang ingin Anda mulai.
Klik MULAI.
Pada dialog, klik MULAI. Status streaming berubah dari Not started menjadi Starting, lalu menjadi Running.
Setelah memulai aliran, Anda dapat memantaunya
untuk memverifikasi bahwa Datastream mentransfer data dari database sumber ke
tujuan.
Menjeda streaming
Setelah memulai streaming, Anda dapat menjedanya. Saat aliran dijeda, Datastream tidak akan menarik data baru dari database sumber ke tujuan. Namun, beberapa data mungkin terus ditulis ke tujuan saat data "dalam proses" terus mengalir.
Dalam beberapa kasus, jika Anda menjeda aliran, database sumber harus menyimpan
data hingga Anda melanjutkan aliran. Periode retensi untuk database sumber mungkin terbatas. Jika aliran data dijeda lebih lama dari
periode retensi sumber, lalu dilanjutkan, hal ini dapat menyebabkan
aliran data gagal. Jika hal ini terjadi, hapus
streaming, buat yang
baru, lalu mulai agar
Datastream dapat mentransfer data, skema, dan tabel dari database
sumber ke tujuan.
Centang kotak di sebelah kiri aliran yang ingin Anda jeda.
Klik JEDA.
Pada dialog, klik JEDA. Status streaming berubah dari Running menjadi Draining. Menguras aliran adalah proses mengosongkan aliran sehingga tidak berisi data apa pun.
Setelah semua data dalam aliran dikosongkan, status aliran akan berubah dari Draining menjadi Paused.
Setelah menjeda aliran, Anda dapat melanjutkannya sehingga
Datastream dapat mentransfer data baru dari database sumber ke
tujuan.
Melanjutkan streaming
Anda dapat melanjutkan streaming yang Anda jeda. Dengan melanjutkan
aliran, Datastream dapat mentransfer data baru dari database sumber ke
tujuan.

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)."]]
