# Amazon Kinesis Data Streams 事件源映射的 Lambda 参数
<a name="services-kinesis-parameters"></a>

所有 Lambda 事件源映射共享相同的 [CreateEventSourceMapping](https://docs.aws.amazon.com/lambda/latest/api/API_CreateEventSourceMapping.html) 和 [UpdateEventSourceMapping](https://docs.aws.amazon.com/lambda/latest/api/API_UpdateEventSourceMapping.html) API 操作。但是，只有部分参数适用于 Kinesis。
