Tried this:
import boto3
from boto3.s3.transfer import TransferConfig, S3Transfer
path = "/temp/"
fileName = "bigFile.gz" # this happens to be a 5.9 Gig file
client = boto3.client('s3', region)
config = TransferConfig(
multipart_threshold=4*1024, # number of bytes
max_concurrency=10,
num_download_attempts=10,
)
transfer = S3Transfer(client, config)
transfer.upload_file(path+fileName, 'bucket', 'key')
Result: 5.9 gig file on s3. Doesn't seem to contain multiple parts.
I found this example, but part
is not defined.
import boto3
bucket = 'bucket'
path = "/temp/"
fileName = "bigFile.gz"
key = 'key'
s3 = boto3.client('s3')
# Initiate the multipart upload and send the part(s)
mpu = s3.create_multipart_upload(Bucket=bucket, Key=key)
with open(path+fileName,'rb') as data:
part1 = s3.upload_part(Bucket=bucket
, Key=key
, PartNumber=1
, UploadId=mpu['UploadId']
, Body=data)
# Next, we need to gather information about each part to complete
# the upload. Needed are the part number and ETag.
part_info = {
'Parts': [
{
'PartNumber': 1,
'ETag': part['ETag']
}
]
}
# Now the upload works!
s3.complete_multipart_upload(Bucket=bucket
, Key=key
, UploadId=mpu['UploadId']
, MultipartUpload=part_info)
Question: Does anyone know how to use the multipart upload with boto3?
