New Features and Improvements

ATSCALE-13425

ATSCALE-12954

2022.4.0

Dimension Calculation Groups

Dimension Calculation Groups offer Data Architects a simplifying alternative to Calculated Measures by enabling the expression of boiler-plate calculations across multiple Measures. This feature defines calculations as dimension members, and removes static references to individual Measures. At run-time, workbook authors evaluate the dimension calculations over an arbitrary set of measures. Using this feature the number of Calculated Measures in a model can be reduced by a factor equal to the number of measures in the model. For details, see Using Dimension Calculation Groups.

ATSCALE-6108

Support for XMLA compression

When using BI clients that use XMLA, you can improve the communication by enabling Xpress compression. You can do this using the new soap.xpress.enabled engine setting.

ATSCALE-10022

ADC-based impersonation for Google BigQuery

When using Google BigQuery as a data warehouse, you can now configure AtScale to use Application Default Credentials (ADC) impersonated with Service Account. For details, see Adding Google BigQuery Data Warehouses.

ATSCALE-12433

Support for Unity Catalog

When using Databricks as a data warehouse you can now use Unity Catalog. For details, see Adding Databricks Data Warehouses.

ATSCALE-9274

Using the %NOJOURN parameter for IRIS

InterSystems IRIS 2022.2 introduces the new %NOJOURN parameter for the create table command. If you use this or newer version of IRIS as a data warehouse, you can enable the new AtScale engine setting aggregates.create.iris.nojourn.enabled to set aggregates to be created with the %NOJOURN keyword. For details, see Settings specific for data warehouses.

ATSCALE-11392

Enabling compression of AtScale aggregates on DB2

When using DB2 as a data warehouse, you can now enable value and row compression, and specify the type of row compression to be used. Enabling compression of AtScale aggregates could lead to improvements in disk space usage. For details, see Settings specific for data warehouses.

ATSCALE-1729

Cube-level settings for aggregates

Many of the aggregate configuration settings can now be set at cube level. For details, see Cube Level Configuration Settings.

ATSCALE-1856

Limiting Dimension-only queries

When using very large dimensions, you can use the new query.language.mdx.dimquery.result.limit setting to set the number of data rows to be returned for Dimension-only queries. For details, see Query Settings.

ATSCALE-13161

Value Column label unified

In previous releases, the dialogs for creating or editing dimensions, levels, and secondary attributes contained a field labeled either Value Column or Name Column. Now this field is labeled Value Column in all of these dialogs.

ATSCALE-4186

Measure filtering for SuperDAX MD

Measure filtering is now supported for SuperDAX MD queries.

ATSCALE-11544

Displaying Query-based datasets

Query-based datasets are now displayed on the canvas with a different color, which differentiates them from the other datasets included in the cube.

ATSCALE-7231

Enhanced message for unsupported aggregation function

The "Unsupported aggregation function used within Aggregate function" message that appeared in the Queries screen is enhanced. It now contains information about the names of the Measure and the Calculation that triggered the error.

ATSCALE-13161

Beta features

AtScale offers Beta support for the following features:

• Using external secret storage

  Support for external secret managers (SM) will give you an opportunity to store all data warehouse passwords in one place (SM), and point AtScale to use this SM instead of typing the credentials manually. In I2022.4.1, AtScale will support this functionality in beta stage, and only Vault and AWS Secret Manager will be the options to use. (ATSCALE-11825)

  In Settings > Organization Settings > Engine there are options for enabling and configuring the SM, like secret.aws.enabled and secret.vault.enabled.

• Starburst

  You can use the Starburst data warehouse. (ATSCALE-12629)

Official support for these features is planned for future releases. If interested in beta testing, please contact your Customer Success Manager.
