gzipstream allows Python to process multi-part gzip files from a streaming source.
The library is originally intended for use with the Python warc library for processing Common Crawl and other web archive data.
If you are using pip, simply run the command pip install -e git+https://github.com/commoncrawl/gzipstream.git#egg=gzipstream.
You can also install using python setup.py install if so desired.
As an example of usage, examples/streaming_commoncrawl_from_s3.py shows how gzipstream can be used to incrementally process a gzipped web archive (WARC) file.
The file is almost a gigabyte in size, selected randomly from the 2014-15 Common Crawl dataset and hosted on Amazon S3.
Without gzipstream, processing of the file would only be possible by fully downloading it.
This is highly inefficient as (a) a gzipped WARC file is composed of multiple independent gzip files and (b) the WARC file is hunderds of megabytes in size.

For minimal usage however...
from gzipstream import GzipStreamFile
f = open('huge_file.gz') # Any streaming file object that supports `read`
gz = GzipStreamFile(f)MIT License, as per LICENSE
