ATSCALE-25717, ATSCALE-25750, ATSCALE-25649, ATSCALE-26356, ATSCALE-25010, ATSCALE-24423

Tableau Server integration​

Multiple issues related to Tableau Server integration have been resolved.

ATSCALE-25271, ATSCALE-24789

Adding metrics or dimensions in Tableau Server resulted in an error​

When the tableau.rawSqlAggs.enabled global/model setting was enabled, adding metrics or dimensions in Tableau Server resulted in an error. This was caused by client-side overrides to metric aggregation.

This issue has been resolved. AtScale can now be configured to prevent client-side aggregation in Tableau Server and Tableau Desktop via the new query.language.sql.preventClientSideAggregation global setting. When enabled, all metrics in .tds files are sent as either averages or distinct counts, and client-side aggregation cannot be performed. This setting is disabled by default. For more information, see Query Settings.

ATSCALE-26286

Expired data warehouse tokens blocked AtScale engine startup​

When a data warehouse had an expired or incorrect token, the AtScale engine got stuck while invalidating aggregates and timed out. This issue has been resolved.

ATSCALE-25826

Redis connections timed out​

The AtScale engine could not connect to Redis after multiple attempts. This issue has been resolved.

ATSCALE-25202

Multiple MDX functions caused errors during query planning​

Queries containing the ExtractMember, Tail, NonEmpty, and Descendants MDX functions caused errors during query planning. This occurred when the expressions contained static references to the All member. This issue has been resolved.

ATSCALE-25836

PostgreSQL interface returned errors for numeric result sets​

When using AtScale with the PostgreSQL interface, the interface returned errors for numeric result sets. This was because, in some circumstances, it expected the results to be formatted in binary, not numeric values.

This issue has been resolved: The internal AtScale PostgreSQL server now returns result sets in the format expected by the PostgreSQL interface.

ATSCALE-25856

Warning during TLS Certificate hashing when installing or upgrading​

The warning during TLS Certificate hashing when installing or upgrading has been fixed.

Engine init container failed due to missing OpenSSL on azul/zulu-openjdk image​
