End-to-end resolution for Snowplow Identities typically completes in low single-digit seconds from event collection to resolved output. Three things move that figure. The event collector latency, the resolver's internal merge processing, and any downstream replication into the warehouse or activation tools. The first two are managed inside Snowplow Identities. The third depends on your destinations: a Kafka or Pub/Sub consumer can see the merge event within a second of resolution, a dbt model on a five-minute schedule will not.
