Polling Operasi yang Berjalan Lama

Halaman ini menjelaskan cara melakukan polling secara terprogram pada resource operasi yang berjalan lama yang ditampilkan oleh metode di Service Infrastructure API yang memerlukan waktu yang cukup lama untuk diselesaikan, seperti service.rollouts.create. Setelah operasi selesai, kolom done akan ditetapkan ke true.

Untuk melakukan polling operasi, panggil berulang kali metode operations.get dengan backoff 10 detik yang direkomendasikan hingga operasi selesai:
