Halaman ini menjelaskan cara melihat pratinjau data di Cloud Data Fusion Studio sehingga Anda dapat men-debug error sebelum men-deploy dan menjalankan pipeline.
Jika mengalami error, Anda dapat memperbaikinya saat pipeline masih dalam mode Draf.
Cloud Data Fusion menggunakan 100 baris pertama set data sumber Anda untuk
membuat pratinjau.
Dalam mode Pratinjau, halaman Studio menampilkan status dan durasi
tugas pratinjau. Anda dapat menghentikan tugas pratinjau kapan saja. Anda juga dapat memantau
peristiwa log saat tugas pratinjau berjalan.
Konsol
Pastikan setiap sumber, transformasi, dan sink tidak memiliki error. Untuk
memvalidasinya, di halaman Studio Cloud Data Fusion, buka
node untuk setiap plugin, lalu klik Properties>Validate.
Lihat pipeline Anda di halaman Studio, lalu klik tombol Pratinjau
ke posisi aktif. Opsi Run, Duration, dan Logs
akan muncul di bagian atas kanvas halaman Studio.
Opsional: sebelum menjalankan tugas pratinjau, perbarui setelan berikut
dengan mengklik Konfigurasi.
Konfigurasi pratinjau: memperbarui jumlah baris yang akan dipratinjau.
Opsi lanjutan: memperbarui konfigurasi pipeline dan mesin.
Untuk mengetahui informasi selengkapnya, lihat Mengelola konfigurasi pipeline.
Untuk memulai tugas pratinjau, klik Run. Saat tugas pratinjau berjalan, tidak ada data yang ditulis ke sink, tetapi Anda dapat memeriksa apakah data dibaca dan ditulis seperti yang diharapkan saat men-deploy pipeline.
Opsional: setelah menjalankan tugas pratinjau, untuk melihat tampilan data Anda di setiap tahap dalam pipeline, klik Pratinjau data pada node dalam pipeline yang menangani data, seperti sumber, sink, dan transformasi.
Setelah selesai melihat pratinjau data, keluar dari mode Pratinjau dengan mengklik tombol Pratinjau ke posisi nonaktif.

You can stop the preview job at any time. You can also monitor\nthe log events as the preview job runs.\n**Note:** Actions and post-run actions are ignored when running a preview. To preview data, follow these steps: \n\n### Console\n\n1. Check that each source, transformation, and sink has no errors. To validate them, on the Cloud Data Fusion **Studio** page, go to the node for each plugin and click **Properties** \\\u003e **Validate**.\n2. View your pipeline on the **Studio** page and click the **Preview** toggle to the on position. **Run** , **Duration** , and **Logs** options appear at the top of the **Studio** page canvas.\n3. Optional: before you run the preview job, update the following settings\n by clicking **Configure**.\n\n 1. **Runtime arguments** : for more information see [Set up runtime arguments](/data-fusion/docs/how-to/manage-macros-prefs-and-runtime-args#set-up-runtime-arguments).\n 2. **Preview config**: update the number of rows to preview.\n 3. **Advanced options** : update the pipeline and engine configurations. For more information, see [Manage pipeline configurations](/data-fusion/docs/concepts/manage-pipeline-configurations).\n4. To start the preview job, click **Run**. When the preview job runs, no\n data is written to the sink, but you can check that data is read\n and written as expected when you deploy the pipeline.\n\n5. Optional: after you run the preview job, to see what your data looks\n like at each stage in the pipeline, click **Preview data** on nodes in\n the pipeline that handle data, such as sources, sinks, and\n transformations.\n\n6. When you're finished previewing the data, exit Preview mode by clicking\n the **Preview** toggle to the off position.\n\nWhat's next\n-----------\n\n- Learn how to [create pipeline alerts](/data-fusion/docs/how-to/create-alerts)."]]
