Code was added in T213817
Once this code as landed in production we should turn on seperate DB connections for wikidata item ID generation.
Config was introduced in https://gerrit.wikimedia.org/r/#/c/mediawiki/extensions/Wikibase/+/485859/2/repo/config/Wikibase.default.php
This should be deployed in 2 stages:
- test.wikidata.org
- wikidata.org
Once deployed on test entity creation should be tested.
Entity creation rate and errors should be watched during the deployment time on wikidata.org
