我有超过一百万个文件位于远程云文件存储服务上,我需要尽快跟踪单个文件是否存在。
由于建立一个可用文件列表需要几分钟,我需要缓存一个列表,但我不确定这里的最佳方式是什么。
跟踪文件列表的最快且资源成本更低的方法是什么?
Most APIs allow you to call the file listing while giving a regular expression for the listing. I know the PHP sdk of AWS supports this on S3. I think that is a faster and more accurate way to do what you want to do.
