我能够直接将文件从URI流式传输到S3，而无需使用this guys sample code使用AWS Lambda（node.js）将其下载到磁盘上。我修改了一下，所以我可以从请求对象体创建一个缓冲区。 This is my code
除了一件非常重要的事情之外，它的确很奇怪！这些文件最大为350 MB，但每次运行lambda函数时，最多需要1.5 GB内存甚至更多！函数调用允许的最大内存为1.536 GB。通常使用的数量介于0.8 GB到1.5 GB之间（非常随机）。
我认为某处存在内存泄漏，但我无法弄清楚在哪里！
有什么想法吗？
答案 0 :(得分：1)
var buffer = new Buffer(body);似乎正在制作内存中整个响应体的副本......将你需要的内存量翻倍。
request似乎提供（或可配置提供）body Buffer，因此您应该能够直接使用body，而不是将其复制到Option Explicit
