Wikifunctions backend services: Gather and propagate freshness info
Closed, ResolvedPublic
Actions

Description

Description

Implement gathering and propagation of freshness info (info regarding use of cached content) in the Orchestrator and Evaluator for result freshening (27Q1 hypothesis).

  • As specified in T433454, for this hypothesis this info only includes the Wikidata entities retrieved from Orchestrator memcached for the current function-call request.
  • This info will be returned to WikiLambda in a de-duplicated list, the value of a new metadata property cachedWikidataEntities. This will be a list of entity IDs (strings).
