I was hoping to use s3fs to upload new files into S3. On the documentation I saw that it doesn't work well when there are multiple clients uploading/syncing to the same bucket.
I really don't care about syncing files from to bucket to my local drive, I only want to perform the opposite: only upload to s3 new files as they are created.
Is there a way to achieve that with s3fs? It wasn't clear on the docs if they offer that functionality by the usage of flags.
s3fs does not synchronize files. Instead it intercepts the open, read, write, etc. calls and relays them to the S3 server. Thus it will work for your upload-only use case. Note that s3fs does use some temporary storage to stage the upload.
