SelfManagedKafka

描述SelfManagedKafka事件來源類型的物件。如需詳細資訊，請參閱《 AWS Lambda 開發人員指南》中的使用 AWS Lambda 搭配自我管理的 Apache Kafka。

AWS Serverless Application Model (AWS SAM) 會在設定此事件類型時產生 AWS::Lambda::EventSourceMapping 資源。

若要使用結構描述登錄檔，您需要定義函數的特定 IAM 角色許可。如需所需組態的範例，請參閱使用 IAM 角色完成設定。

語法

若要在 AWS SAM 範本中宣告此實體，請使用下列語法。
