## Production Run

At git commit `6ad9d24e4d7d901d6fc394e6e91575f6acba7ff4`.

Start small:

    export FATCAT_AUTH_WORKER_CLEANUP=[...]

    zcat /srv/fatcat/datasets/files_20211105_moreshortts.fetched.json.gz \
        | head -n100 \
        | python -m fatcat_tools.cleanups.file_short_wayback_ts -
    # Counter({'total': 100, 'update': 99, 'skip-bad-wayback-timestamp': 1, 'skip': 0, 'insert': 0, 'exists': 0})

Looks good! Run the full batch.

    zcat /srv/fatcat/datasets/files_20211105_moreshortts.fetched.json.gz \
        | pv -l \
        | parallel -j8 --linebuffer --round-robin --pipe python -m fatcat_tools.cleanups.file_short_wayback_ts -

On the order of 99.7% were updated/fixed, over 9.5 million file entities, taking almost 13 hours.

## Production Follow-up (2021-11-29)

Fixed a small bug in `fetch_full_cdx_ts.py` helper script, and running import
again:

    git log | head -n1
    # commit ec2809ef2ac51c992463839c1e3451927f5e1661

    export FATCAT_AUTH_WORKER_CLEANUP=[...]

    zcat /srv/fatcat/datasets/files_20211127_moreshortts.fetched.json.gz | wc -l
    # 29494

    zcat /srv/fatcat/datasets/files_20211127_moreshortts.fetched.json.gz \
        | pv -l \
        | python -m fatcat_tools.cleanups.file_short_wayback_ts -
    # Counter({'total': 29494, 'update': 21358, 'skip': 8126, 'skip-status': 7677, 'skip-bad-replacement': 449, 'skip-bad-wayback': 9, 'skip-bad-wayback-timestamp': 1, 'insert': 0, 'exists': 0})

That caught 72% of the outstanding files. At this point would almost be willing
to just remove the outstanding bad URLs (possibly leaving the files with no
access options), but might also be worth revisiting in the future to trace down
exactly what is going on.
