TASK DESCRIPTION
As a user, if there is catastrophic data loss in Wikidata, I want to keep the
N top-ranked statements in order to maximize my ability to continue querying a
reduced graph.
- What is the distribution of top-ranked statements to least-ranked?
- Is it easy/possible to separate top-ranked statements from least ranked?
- If so, roughly how large is the set of top-ranked statements?
- How disruptive would removing least-ranked statements be?
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.
