问题
My Amazon S3 bucket has millions of files and I am mounting it using s3fs. Anytime a ls command is issued (not intentionally) the terminal hangs.
Is there a way to limit the number of results returned to 100 when a ls command is issued in a s3fs mounted path?
回答1:
Try goofys (https://github.com/kahing/goofys). It doesn't limit the number of item returned for ls, but ls is about 40x faster than s3fs when there are lots of files.
回答2:
It is not recommended to use s3fs in production situations. Amazon S3 is not a filesystem, so attempting to mount it can lead to some synchronization issues (and other issues like you have experienced).
It would be better to use the AWS Command-Line Interface (CLI), which has commands to list, copy and sync files to/from Amazon S3. It can also do partial listing of S3 buckets by path.
