## SQL Table Sizes
SELECT
table_name,
pg_size_pretty(table_size) AS table_size,
pg_size_pretty(indexes_size) AS indexes_size,
pg_size_pretty(total_size) AS total_size
FROM (
SELECT
table_name,
pg_table_size(table_name) AS table_size,
pg_indexes_size(table_name) AS indexes_size,
pg_total_relation_size(table_name) AS total_size
FROM (
SELECT ('"' || table_schema || '"."' || table_name || '"') AS table_name
FROM information_schema.tables
WHERE table_schema = 'public'
) AS all_tables
ORDER BY total_size DESC
) AS pretty_sizes;
## File Metadata
Counts and total file size:
SELECT COUNT(*) as total_count, SUM(size_bytes) as total_size FROM file_meta;
Top mimetypes:
SELECT mimetype, COUNT(*) FROM file_meta GROUP BY mimetype ORDER BY COUNT DESC LIMIT 10;
Missing full metadata:
SELECT COUNT(*) FROM file_meta WHERE sha256hex IS NULL;
## CDX
Total and unique-by-sha1 counts:
SELECT COUNT(DISTINCT sha1hex) as unique_sha1, COUNT(*) as total FROM cdx;
Processed or not:
# TODO:
## GROBID
Counts:
SELECT COUNT(DISTINCT fatcat_release) AS unique_releases, COUNT(*) AS total FROM grobid;
Status?
SELECT status_code, COUNT(*) FROM grobid GROUP BY status_code ORDER BY COUNT DESC LIMIT 10;
What version used?
SELECT grobid_version, COUNT(*) FROM grobid WHERE status_code = 200 GROUP BY grobid_version ORDER BY COUNT DESC LIMIT 10;
## Petabox
Counts:
SELECT COUNT(DISTINCT sha1hex) as unique_sha1, COUNT(*) as total FROM petabox;
## Ingests
Requests by source:
SELECT ingest_type, link_source, COUNT(*) FROM ingest_request GROUP BY ingest_type, link_source ORDER BY COUNT DESC LIMIT 25;
Uncrawled requests by source:
# TODO: verify this?
SELECT ingest_request.ingest_type, ingest_request.link_source, COUNT(*)
FROM ingest_request
LEFT JOIN ingest_file_result
ON ingest_request.base_url = ingest_file_result.base_url
AND ingest_request.ingest_type = ingest_file_result.ingest_type
WHERE ingest_file_result.base_url IS NULL
GROUP BY ingest_request.ingest_type, ingest_request.link_source ORDER BY COUNT DESC LIMIT 25;
Results by source:
SELECT
ingest_request.ingest_type,
ingest_request.link_source,
COUNT(*) as attempts,
COUNT(CASE WHEN ingest_file_result.hit THEN 1 END) hits,
ROUND(1.0 * COUNT(CASE WHEN ingest_file_result.hit THEN 1 END) / COUNT(*), 3) as fraction
FROM ingest_request
LEFT JOIN ingest_file_result
ON ingest_request.base_url = ingest_file_result.base_url
AND ingest_request.ingest_type = ingest_file_result.ingest_type
AND ingest_file_result.ingest_type IS NOT NULL
GROUP BY ingest_request.ingest_type, ingest_request.link_source ORDER BY attempts DESC LIMIT 25;
Ingest result by status:
SELECT ingest_type, status, COUNT(*) FROM ingest_file_result GROUP BY ingest_type, status ORDER BY COUNT DESC LIMIT 25;
## Fatcat Files
Count of PDF files that GROBID processed and matched to a release (via
glutton), but no PDF in `fatcat_file`:
SELECT COUNT(*) as total_count, COUNT(DISTINCT grobid.fatcat_release) as release_count
FROM grobid
LEFT JOIN fatcat_file ON grobid.sha1hex = fatcat_file.sha1hex
WHERE fatcat_file.sha1hex IS NULL
AND grobid.fatcat_release IS NOT NULL;
