As a user, I want to know the potential cost/benefit estimates for splitting off astronomical objects from the Wikidata graph, so that WDQS can scale to my needs.
This ticket is a part of WDQS disaster planning, and reflects research into mitigation strategies for catastrophic failure of Blazegraph: specifically in the case that the Wikidata graph becomes too big for Blazegraph to continue supporting. This is not a commitment to a long term state of WDQS or Wikidata, but part of the disaster mitigation playbook in a worst case scenario.
For astronomical objects in Wikidata (https://www.wikidata.org/wiki/Q6999):
- Determine the size in Blazegraph (actual, percentage), and how much runway time deleting it gains us at current Wikidata growth rate.
- Estimate how many queries reference/touch astronomical objects in Wikidata graph
