Contoh Kinesis menggunakan for SDK SAP ABAP

Contoh kode berikut menunjukkan cara melakukan tindakan dan mengimplementasikan skenario umum dengan menggunakan AWS SDK for SAP ABAP with Kinesis.

Dasar-dasar adalah contoh kode yang menunjukkan kepada Anda bagaimana melakukan operasi penting dalam suatu layanan.

Tindakan adalah kutipan kode dari program yang lebih besar dan harus dijalankan dalam konteks. Sementara tindakan menunjukkan cara memanggil fungsi layanan individual, Anda dapat melihat tindakan dalam konteks dalam skenario terkait.

Setiap contoh menyertakan tautan ke kode sumber lengkap, di mana Anda dapat menemukan instruksi tentang cara mengatur dan menjalankan kode dalam konteks.

Hal-hal mendasar

Contoh kode berikut ini menunjukkan cara:

Buat aliran dan letakkan catatan di dalamnya.
Buat iterator shard.
Baca catatan, lalu bersihkan sumber daya.
