+Rough plan:
+
+- run bulk and/or regular ingest requests for just those of AIT partners (200k?)
+- persist ingest requests (22 million or so)
+- run bulk ingest over 'no status' / 'no match' requests (aka, those not in unpaywall)
+- crawl those which are no-capture
+
+
+## Generate Requests
+
+Newer version of `mag_ingest_request.sh` script requires venv with urlcanon
+installed.
+
+Starting with the 2020-01-23 MAG dump, will generate a full ingest request set
+(including DOI `ext_id` when available), with any dominant domains removed (eg,
+arxiv.org):
+
+ export LC_ALL=C
+ cat PaperUrls_mag_url_doi.all.txt | rg -a -v arxiv.org | rg -a "://" | ./mag_ingest_request.py - --created-date 2020-01-23 | pv -l > ingest_requests_mag-2020-01-23.doi.json
+ => previously 25.6M
+ => 25.6M 2:29:43 [2.85k/s]
+
+ export LC_ALL=C
+ zcat PaperUrls_mag_url_pmid.txt.gz | rg -a -v arxiv.org | rg -a "://" | ./mag_ingest_request.py - --created-date 2020-01-23 --pmid | pv -l > ingest_requests_mag-2020-01-23.pmid.json
+ => 4.3M 0:25:45 [2.78k/s]
+
+ export LC_ALL=C
+ cat ingest_requests_mag-2020-01-23.json | jq -r "[.base_url, .ext_ids.doi] | @tsv" | sort -u -S 4G > ingest_requests_mag-2020-01-23.full.seed_id
+
+ zcat PaperUrls_PaperExtendedAttributes_pdf.txt.gz | wc -l
+ => 6,504,907
+
+ zcat PaperUrls_mag_url_pmid.txt.gz | wc -l
+ => 4,369,832
+
+ cat ingest_requests_mag-2020-01-23.json | jq .ext_ids.doi -r | rg -a -v '^null$' | wc -l
+ => previously 15,707,405
+ => 15,702,581
+
+ cat ingest_requests_mag-2020-01-23.pmid.json | jq .base_url -r | rg ' ' | wc -l
+ => 0
+ URL encoding seems to be working
+
+## Persist Ingest Requests
+
+First pmid ingest requests, then the all/doi file. The reason to do this order
+is that the all/doi file will have some rows with no DOI (and thus no
+`ext_id`), while the PMID file will not.
+
