Undispatched change distribution

Fork of Undispatched change distribution by Lucas Werkmeister (WMDE)

This query is marked as a draft This query has been published by Lucas Werkmeister (WMDE).

This shows the number of Wikidata edits that have to be dispatched to English Wikipedia per ten-minute interval. The idea is to get some vague understanding of how the dispatch lag will develop as changes keep being dispatched at what is presumably a near-constant rate. (The best way to look at the results is probably to download/open them in XLSX format and having LibreOffice chart them.)

SQL

USE `wikidatawiki_p`;

SELECT SUBSTRING(`change_time` FROM 1 FOR 11) AS `ten_minute_interval`, COUNT(*) AS `count`
FROM `wb_changes`
JOIN `wb_changes_subscription` ON `cs_entity_id` = `change_object_id`
WHERE `cs_subscriber_id` = "enwiki"
AND `change_id` >= (SELECT `chd_seen` FROM `wb_changes_dispatch` WHERE `chd_site` = "enwiki")
GROUP BY `ten_minute_interval`
ORDER BY `ten_minute_interval`
