The querier is a stateless component that evaluates queries expressions by fetching profiles series and labels on the read path.
Connecting to ingesters
You must configure the querier with the same
-ingester.ring.* flags (or their respective YAML configuration parameters) that you use to configure the ingesters so that the querier can access the ingester hash ring and discover the addresses of the ingesters.
For details about querier configuration, refer to querier.
