Use reports database to obtain data automatically in reports (8.3)
When configuring a report definition, the report now automatically queries the default reporting database unless you specify that it queries the standard database or a class-level reporting database. This provides support for reporting against Amazon Aurora read replicas.
You can change which database a report definition obtains data from in the Reporting database field in the Data access tab, as shown in the following image. This feature is also supported on Pega Cloud Services.
For more information, see Report definition data access tab.
