OpenSearch Exemplos de serviços usando SDK para Java 2.x

Os exemplos de código a seguir mostram como realizar ações e implementar cenários comuns usando o AWS SDK for Java 2.x with OpenSearch Service.

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.
