Kinesis 示例使用 SDK SAP ABAP

下列程式碼範例說明如何使用 to SAP ABAP 搭配 Kinesis 來執行動作和實作常見案 AWS SDK例。

基本概念是程式碼範例,會示範如何在服務中執行基本作業。

Actions 是大型程式的程式碼摘錄,必須在內容中執行。雖然動作會顯示如何呼叫個別服務函數,但您可以在其相關案例中查看內容中的動作。

每個範例都包含完整原始程式碼的連結,您可以在其中找到如何在內容中設定和執行程式碼的指示。

基本概念

以下程式碼範例顯示做法:

  • 創建一個流並在其中放置一條記錄。

  • 創建一個碎片迭代器。

  • 閱讀記錄,然後清理資源。
