Since the recent preview, Query Store raised great interest among users as an effective solution to provide insight on query performance. Microsoft announced the general availability of Query Store for Azure SQL Data Warehouse worldwide.
When monitoring a data warehouse, Query Store captures query history, separates the data by time slots and provides an overview of the database usage patterns.
