Preprocessing

parse.py

Parse raw json data files into three pickle data files.

• output-data-basename.user: map of user id (str) to user name (str)
• output-data-basename.repo: map of repo id (int) to repo name (str)
• output-data-basename.edge: list of tuples of user-repo edge (str, int)

Usage: parse.py {-m|--member|-w|--watch} {<input-json-directory>|<input-json-file>} <output-data-basename>
  -m, --member      parse MemberEvent.
  -w, --watch       parse WatchEvent.
Ex:    parse.py -m 2017-06-01-0.json data
Ex:    parse.py --watch json/2017-05/ data/2017-05

Refer raw json data format to GitHub API v3.

parse_mp.py

Ditto, but run with multiprocessing. Default number of processes is 16.

Usage: parse_mp.py {-m|--member|-w|--watch} {<input-json-directory>|<input-json-file>} <output-data-basename> [n-process]
  -m, --member      parse MemberEvent.
  -w, --watch       parse WatchEvent.
  n-process         number of processes when multiprocessing.
Ex:    parse.py -m 2017-06-01-0.json data
Ex:    parse.py --watch json/2017-05/ data/2017-05 32

mergedata.py

Merge multiple pickle data files into one.

Usage: mergedata.py <input-data-dir> <output-data-basename>
Ex:    mergedata.py data/2016-010203/ data/2016-Q1

graph2redis.py

Insert graph data into redis database.

Usage: graph2redis.py <input-edgelist> <redis-port>
Ex:    graph2redis.py data/2016-Q1.edge 6379
