Set up historical retention
Historical retention ensures your data changes are stored for a specific duration. Configuring this at the database level is simple:
CREATE OR REPLACE DATABASE my_database DATA_RETENTION_TIME_IN_DAYS = 30;
Query historical data
Historical data queries allow you to access and analyze data as it appeared at a specific point in time:
SELECT *
FROM your_table
AT(TIMESTAMP => '2023-08-13 01:00:00'::timestamp);
Audit changes
To keep track of modifications, you can use a Snowflake stream. This feature helps maintain an audit trail of all changes:
CREATE OR REPLACE STREAM change_stream ON TABLE your_table;
