Summary
Turn topk aggregation into a two-part flow: write an expire tracker row after each score row (when
Topk.expireAfterMillis > 0), and sweep expired rows in bulk via a new endpoint. Together these let downstream jobs re-aggregate stale topk entries without walking the score table itself.Changes
topk.expireafter every successful score write inAggregationService.aggregateTopk, keyed byAggregationConstants.expireSource/expireTarget.AggregationService.expires+POST /graph/v3/aggregations/expire. Items are deduped by(database, table, source)and swept withexpiresAt:lte:max(expiresAt)on theexpires_at_ascindex.source/targeton each expire row so the touch-line CDC can rebuild the topk event viaEdgeAggregationEvent.of(expire).expireSourcetoXXHash32Wrapper+mod 2310so writes land on the intended 2310 partitions.How to Test
