Pyroscope querier

The querier is a stateless component that evaluates queries expressions by fetching profiles series and labels on the read path.

The querier uses the ingester component only to query recently written data. The support of querying the long-term storage is planned for the next release.

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.
