Known Issues
Before installing or upgrading AtScale, please review this section to be aware of all known issues.
C2025.6.4
Underscore-led tables do not display
Schemas that lead with underscores do not appear in AtScale. Any schemas that lead with underscores should be updated so they display properly.
ATSCALE-17613
Enabling honeybee on PostgreSQL data warehouses causes engine instability
Enabling honeybee on a PostgreSQL data warehouse after it has been connected to AtScale causes the engine to become unstable. To avoid this issue, AtScale recommends enabling honeybee on your PostgreSQL data warehouse before adding it in Design Center.
ATSCALE-28082
ADDCOLUMNS DAX function results in failure
When using Microsoft Power BI in Tabular mode with Redshift, adding a Power BI client-side expression with the ADDCOLUMNS DAX function can result in errors.
ATSCALE-25366
Is Aggregatable cannot be disabled on non-root levels in hierarchies with more than two levels
In hierarchies with more than two levels, disabling the Is Aggregatable property on levels other than the root level is not supported. In future releases, models with such a configuration will not deploy to the engine.
ATSCALE-25328
Iris JDBC does not support CTEs
The Iris JDBC driver does not support Common Table Expressions (CTEs), so the new feature that enables the query planner to use CTEs is not supported for Iris. If you are using AtScale on Iris, you need to set the following global setting:
query.planning.allowCtes: false
By default, this setting is set to true.
For models with more than 1600 attributes, AtScale fails to answer all PostgreSQL metadata queries from BI tools
When connected to BI tools via the PostgreSQL interface, AtScale fails to answer all metadata queries on models that have more than 1600 attributes. This is due to a limitation of the PostgreSQL database used to answer these queries.
ATSCALE-22911
Identity Broker logout does not completely log out of Design Center
Users who log in to the Identity Broker from Design Center, then log out of the Identity Broker, are not automatically logged out of Design Center. This is because the Identity Broker logout event interrupts the Design Center function.
ATSCALE-22180
Tableau: Double dashes in catalog names creates empty .tds files
Double dashes (--) in the unique names of catalogs causes corruption of Tableau .tds file generation. This is because double dashes are reserved in many databases, and signal a comment in SQL. AtScale recommends avoiding this character pattern when creating and deploying catalogs.
ATSCALE-16605, ATSCALE-22167
Perspectives cannot contain multiple objects with the same display names
Perspectives cannot contain references to multiple objects with the same display names/labels, as this results in errors at deploy time.
ATSCALE-22326
C2025.6.3
Underscore-led tables do not display
Schemas that lead with underscores do not appear in AtScale. Any schemas that lead with underscores should be updated so they display properly.
