根因分析
Lambda同步调用的负载超过6 MB限制,包括请求和响应大小。
English
Lambda synchronous invocation payload exceeds the 6 MB limit, including both request and response sizes.
官方文档
https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-limits.html解决方案
-
Use asynchronous invocation (Event invoke) which has a 256 KB payload limit, but for larger payloads, upload data to S3 first and pass the S3 key to Lambda. Example: s3_client.upload_fileobj(data_stream, bucket, key); lambda_client.invoke(FunctionName='myFunc', Payload=json.dumps({'s3_key': key})) -
Reduce payload size by filtering unnecessary fields or using pagination. If using API Gateway, enable payload compression.
无效尝试
常见但无效的做法:
-
90% 失败
Lambda服务在检查大小前不会解压,压缩后的数据仍会被视为原始大小。
-
60% 失败
分割负载会增加复杂性和延迟,且可能导致数据一致性问题。
