ORES articletopic scores pushed into Kafka via T240549: Configure ORES to publish new drafttopic scores to Kafka need to get to HDFS somehow, and new scores for the same page need to override old scores. Presumably EventGate can handle this.
- Index via title or page ID? The first is less efficient and less robust, but would allow cross-wiki lookups, which might or might not be needed while articletopic is enwiki-only.
- Do we need a mechanism to get rid of data for deleted pages?
