# Exemplos do Kinesis usando o SDK para SAP ABAP
<a name="sap-abap_kinesis_code_examples"></a>

Os exemplos de código a seguir mostram como realizar ações e implementar cenários comuns usando o AWS SDK para SAP ABAP com 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 perfis de serviço individuais, você pode ver as ações no contexto em seus cenários relacionados.

Cada exemplo inclui um link para o código-fonte completo, em que você pode encontrar instruções sobre como configurar e executar o código.

O exemplo de código a seguir mostra como:
+ Criar um fluxo e inserir um registro nele.
+ Criar um iterador de fragmento.
+ Ler o registro e, em seguida, limpar os recursos.
