[!INCLUDE sqlserver2025-asdb]
Contains information about Query Store replicas, when Query Store for readable secondaries is enabled. You can use this information to determine what replica_group_id to use when using Query Store to force or unforce a plan on a secondary replica with sys.sp_query_store_set_query_hints.
Query Store for secondary replicas is supported starting in [!INCLUDE sssql25-md] and later versions, and in Azure SQL Database. For complete platform support, see Query Store for secondary replicas.

This catalog view returns the same row data on all replicas. The catalog view contains a row per replica for every role_type where it was observed. For example, a two-replica availability group initially contains two rows. After a failover, it contains four rows: one row for each replica in both the primary and secondary roles.
Requires the VIEW DATABASE STATE permission.
