I am trying to load one of my S3 buckets.
File i am trying to load is huge tarball on the web, I don't want to download file on my disk and then again start uploading it to S3 bucket.
is there any way that I can directly specify this URL and it get added to S3 ?
You have to "put" to S3, and it does not "get".

I have built object storage plugin to store orthanc data in s3 bucket in legacy mode. I am now trying to eliminate local storage of files of orthanc and move it to s3 completely. I also have OHIF viewer integrated which is serving orthanc data, How do I make it fetch from s3 bucket? I have read that json file of dicom file can be used to do this, but I dont know how to do that because the json file has url of each instance in s3 bucket. How do i generate this json file if this is the way to do it?
My idea is this: I have an SFTP host with data on it and I want to create a file in S3 from this data, but to save network resources I don't want to download all of this data to a system first to upload again. So my question is: is it possible to transfer the data directly to the s3 without first downloading it? (preferably with the Amazon S3 Java SDK)
I have an S3 bucket and the URL of a large file. I would like to store the content located at the URL in the S3 bucket.
I could download the file to my local machine and then upload it to S3 with Cloudberry or Jungledisk or whatever. However, if the file is large, this may take a long time because the file must be transferred twice, and my network connection is much slower than Amazon's.
If I have a lot of data to store in S3, I can start an EC2 instance, retrieve the files to the instance with curl or wget, and then push the data from the EC2 instance to S3. This works, but it's a lot of steps if I just want to archive one file.
Any suggestions?
You can stream the file directly from the source to S3.
If you are using node, you can use streaming-s3.
I'd like to write a script that can take a list of urls for some files on S3 and upload them directly to a LightSail instance. I know I can download the files from S3 and use sftp to upload to LightSail, but I'm hoping there is a way that I can trigger the file transfer directly from S3 to LightSail. Has anyone done this before?
I have a 17.7GB file on S3. It was generated as the output of a Hive query, and it isn't compressed.
I know that by compressing it, it'll be about 2.2GB (gzip). How can I download this file locally as quickly as possible when transfer is the bottleneck (250kB/s).
I've not found any straightforward way to compress the file on S3, or enable compression on transfer in s3cmd, boto, or related tools.
S3 does not support stream compression nor is it possible to compress the uploaded file remotely.
If this is a one-time process I suggest downloading it to a EC2 machine in the same region, compress it there, then upload to your destination.

Serving gzipped CSS and JavaScript from Amazon CloudFront via S3
Late answer but I found this working perfectly.
aws s3 sync s3://your-pics .
for file in "$(find . -name "*.jpg")"; do gzip "$file"; echo "$file"; done
aws s3 sync . s3://your-pics --content-encoding gzip --dryrun
This will download all files in s3 bucket to the machine (or ec2 instance), compresses the image files and upload them back to s3 bucket.
Verify the data before removing dryrun flag.
There are now pre-built apps in Lambda that you could use to compress images and files in S3 buckets. So just create a new Lambda function and select a pre-built app of your choice and complete the configuration.
Step 1 - Create a new Lambda function
Step 2 - Search for prebuilt app
Step 3 - Select the app that suits your need and complete the configuration process by providing the S3 bucket names.
