Usage

Command Line

$ s3-tar -h

Import

from s3_tar import S3Tar

bucket = 'YOUR_BUCKET_NAME'
path_to_tar = 'PATH_TO_FILES_TO_CONCAT'
tared_file = 'FILE_TO_SAVE_TO.tar'  # use `tar.gz` or `tar.bz2` to enable compression
# Setting this to a size will always add a part number at the end of the file name
min_file_size = '50MB'  # ex: FILE_TO_SAVE_TO-1.tar, FILE_TO_SAVE_TO-2.tar, ...
# Setting this to None will create a single tar with all the files
# min_file_size = None

# Init the job
job = S3Tar(bucket, tared_file,
            min_file_size=min_file_size,
            # target_bucket=None,  # Default: source bucket. Can be used to save the archive into a different bucket
            # cache_size=5,  # Default 5, Number of files to hold in memory to be processed
            # session=boto3.session.Session(),  # For custom aws session
)
# Add files, can call multiple times to add files from other directories
job.add_files(path_to_concat)
# Add a single file at a time
job.add_file('some/file_key.json')
# Star the tar'ing job after files have been added
job.tar()
