Data Redundancy

Data Classification

Catalog Format Dataset Classification Notes
Harvest JSON link_list create, delete
Harvest JSON archive_link_list create revise sync calls - do not use delete switch
Harvest JSON discussion create, (delete - only affects 2 most recent months) Restructure the storage, move date to year=2023/month=09
Pipeline Parquet raw/link_list create, delete (2x daily)
Pipeline Parquet dedupe/link_list create, delete (2x daily)
Pipeline Parquet compacted_raw/link_list create, delete (~weekly)

Sync

Pull Discussions

This has to be done separately because the remote harvester host will not have the full discussion archive. Remote will have the current and previous month, which can be pulled with --delete.

cd /opt/cypherpunk/data/reddit/json
find discussion -name '2023-09' -type d | awk '{print "rsync -avz --size-only --delete www.iterativechaos.com:/opt/cypherpunk/data/reddit/json/"$1"/ ./"$1"/"}'

Pull All Other JSON

rsync -avz --size-only --delete www.iterativechaos.com:/opt/cypherpunk/data/reddit/json/link_list/ /opt/cypherpunk/data/reddit/json/link_list/
rsync -avz --size-only www.iterativechaos.com:/opt/cypherpunk/data/reddit/json/archive_link_list/ /opt/cypherpunk/data/reddit/json/archive_link_list/
