The upload_file method is handled by the S3 Transfer Manager, this means that it will automatically handle multipart uploads behind the scenes for you, if necessary. They provide a higher-level abstraction than the raw, low-level calls made by service clients. session. The code above will result in the output, as shown in the demonstration below. Resources represent an object-oriented interface to Amazon Web Services (AWS). To copy an object using the low-level API, do the following: Initiate a multipart upload by calling the AmazonS3Client.initiateMultipartUpload () method. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide. The only way to modify object metadata is to make a copy of the object and set the metadata. When uploading, downloading, or copying a file or S3 object, the AWS SDK for Python automatically manages retries, multipart and non-multipart transfers. The name of the object is the full path from the bucket root, and any object has a key which is unique in the bucket. The boto3 SDK actually already gives us one file-like object, when you call GetObject. The upload_fileobjmethod accepts a readable file-like object. decorating with streamers and balloons. There's a similar issue on aws-cli: aws/aws-cli#2403 It looks like this just needs some better range checking before seek. #Creating S3 Resource From the Session. Initially I've set the AWS credentials in the Dockerfile using ENV, and later switch to binding /home/$USER/.aws/ to the container to /root/.aws/.

So here, to match the initial example: client = boto3.client('s3') client.upload_fileobj(buff2, bucket, key) would become By selecting S3 as data lake, we separate storage from compute. This is how you can upload files to S3 from Jupyter notebook and Python using Boto3. I apologize for bringing both of the libraries into this, but the code I am testing in real life still uses both (definitely trying to get rid of all the boto code and fully migrate to boto3 but that isn't going to happen right away). If we can get a file-like object from S3, we can pass that around and most libraries won't know the difference! Option 1: moto. As explained here using the method put_object rather than upload_fileobj would just do the job right with io.STRINGIO object buffer. After you upload the object, you cannot modify object metadata.
