What would you like to do?
Python program to Stream data from a URL and upload it directly to S3 without saving it to local disk. This program is very suitable to use in AWS Lambda functions. This works well with large files. This program acts like a relay between the source and the S3. For more details refer to https://amalgjose.com/2020/08/13/python-program-to-stream-da…
import boto3
import requests
authentication = {"USER": "", "PASSWORD": ""}
payload = {"query": "some query"}
session = requests.Session()
response = session.post("URL",
data=payload,
auth=(authentication["USER"],
authentication["PASSWORD"]), stream=True)
s3_bucket = "bucket_name"
s3_file_path = "path_in_s3"
s3 = boto3.client('s3')
with response as part:
part.raw.decode_content = True
conf = boto3.s3.transfer.TransferConfig(multipart_threshold=10000, max_concurrency=4)
s3.upload_fileobj(part.raw, s3_bucket, s3_file_path, Config=conf)
