Serving
Serving is the read path of the platform. Analysts, dashboards and external API consumers never scan raw lake files directly — they submit SQL to the distributed query engine or request governed metrics from the semantic layer, which translates business definitions into warehouse SQL with row-level policies applied.
Responsibility in one sentence
Execute federated SQL over the lakehouse, cache hot results, throttle abusive queries, and resolve governed metrics into policy-aware SQL.
