Memulai (AWS SDK for Python (Boto3))

Program berikut adalah contoh penggunaan Amazon Kendra dalam program Python. Program melakukan tugas berikut:

1. Membuat indeks baru menggunakan CreateIndexoperasi.

2. Menunggu pembuatan indeks selesai. Ini menggunakan DescribeIndexoperasi untuk memantau status indeks.

3. Setelah indeks aktif, ia menciptakan sumber data menggunakan CreateDataSourceoperasi.

4. Menunggu pembuatan sumber data selesai. Ini menggunakan DescribeDataSourceoperasi untuk memantau status sumber data.

5. Ketika sumber data aktif, itu menyinkronkan indeks dengan konten sumber data menggunakan StartDataSourceSyncJoboperasi.
