Data Processing Process

1. $ python step_01_get_link_lists.py
   1. Pulls 24h top 100 every 4 hours
   2. Pulls 7d top 1,000 every 24 hours
   3. Stores as json.bz2, in pages of 100 links.
2. $ python step_02_parquet_link_list.py
   1. Union all of json.bz2 rows into Parquet (ie: raw layer).
   2. Uses compaction, gets slow after about a week without a compaction run.
3. $ python step_03_dedupe_link_list_parquet.py
   1. Takes the most recent entry for each link_id from the raw layer.
   2. Writes to parquet subreddit/day files.
4. $ python step_04_get_discussions.py
   1. Finds discussions above a threshold of comments and upvotes.
   2. Downloads the discussion and stores as json.bz2.
   3. Skips download if a file exists and no more than 20% increase in comments.
   4. TODO: should do a "final download" after a week (or whatever).
5. $ python step_05_discussion_to_gpt.py
   1. Finds the top couple discussions in a set of subreddits.
   2. Pulls the top N tokens worth of comments from each discussion.
   3. Sends to GPT to summarize.
   4. Writes each summary to html/summary/{link-id}.html
   5. Writes the list to archive/gpt_stories_{edition_id}.json
6. $ python step_06_gpt_to_html.py
   1. Loads the 10 most recent gpt_stories_*.json
   2. generates the news.html file.
7. $ rsync -avz html/summary /var/www/html/
8. $ cp html/news.html /var/www/html/
