Data warehouses are optimized in terms of data aggregation and association, but certain features of standard databases, such as transactional properties and data manipulation operations (add, delete, modify) may be compromised or become unavailable.

Cluster management View the cluster status, modify cluster configurations, add cluster tags, and scale out, restart, and delete the cluster. GaussDB(DWS) Cluster Management Snapshot management Create snapshots to back up and restore the cluster.
ELSIF 'PART_' || V_ID = 'PART_2018' THEN DELETE FROM product_list WHERE Year_Manufacture IN (2018); ELSIF 'PART_' || V_ID = 'PART_2019' THEN DELETE FROM product_list WHERE Year_Manufacture IN (2019); ELSIF 'PART_' || V_ID = 'PART_2020' THEN DELETE FROM product_list

Stopping Billing If you no longer need to use your GaussDB(DWS) resources, you can unsubscribe from or delete them to stop the billing. For details, see Stopping Billing. Cost Management GaussDB(DWS) costs include costs of ownership and O&M.
You are advised to use column-store tables for computing service scenarios (mainly involving association and aggregation operations) and row-store tables for service scenarios, such as point queries and massive UPDATE or DELETE executions.
Function Plan hints can be specified using the keywords such as SELECT, INSERT, UPDATE, MERGE, and DELETE, in the following format: 1 /*+ <plan hint> */ You can specify multiple hints for a query plan and separate them by spaces.
The following DML statements support synonyms: SELECT, INSERT, UPDATE, DELETE, EXPLAIN, and CALL. The CREATE SYNONYM statement of an associated function or stored procedure cannot be used in a stored procedure.
