支持事件模式后,AppSync 现在可以异步触发 Lambda 函数,从而将 API 响应与 Lambda 执行分离。对于长时间运行的操作(例如,启动生成式 AI 模型推理,以及利用 Lambda 函数通过 AppSync WebSockets 向客户端发送模型响应)、批处理(例如,启动数据库处理任务)或不需要立即响应的场景(例如,创建消息并将消息放入队...
使用这两个功能,当满足以下两个条件之一时,事件将丢弃,或者发送到死信队列和/或Lambda 目标:重试次数达到最大值,或者事件期限达到最大值。 您可以通过AWS 管理控制台,AWS CLI、AWS CloudFormation 或适用于 Lambda 的 AWS 开发工具包使用这两个功能。在推出 AWS Lambda 的所有 AWS 区域都可以免费...
