Exemplos de Kinesis usando for SDK SAP ABAP

Os exemplos de código a seguir mostram como realizar ações e implementar cenários comuns usando o AWS SDK for SAP ABAP with Kinesis.

As noções básicas são exemplos de código que mostram como realizar as operações essenciais em um serviço.

Ações são trechos de código de programas maiores e devem ser executadas em contexto. Embora as ações mostrem como chamar funções de serviço individuais, você pode ver as ações no contexto em seus cenários relacionados.

Cada exemplo inclui um link para o código-fonte completo, onde você pode encontrar instruções sobre como configurar e executar o código no contexto.

Conceitos básicos

O exemplo de código a seguir mostra como:

Criar um stream e inserir um registro nele.
Criar um iterador de fragmento.
Ler o registro e, em seguida, limpar os recursos.
