New memory options for Analysis Services

05-02-2019  0 Comment(s)

IsAvailableInMdx
The IsAvailableInMdx column property is available in Azure Analysis Services and SQL Server Analysis Services 2017 CU7.

It prevents building attribute hierarchies, reducing memory consumption. This means the column is not available for group-by queries to MDX clients like Excel. Fact (transactional) table columns often don’t need to be grouped and are often the ones that use up the most memory.

This property can also improve performance of refresh operations; particularly for tables with lots of partitions. Building attribute hierarchies can be very expensive because they’re built over all the data in the table.

Currently, this property is not yet exposed in SSDT. It must be set in the JSON-based metadata by using Tabular Model Scripting Language (TMSL) or the Tabular Object Model (TOM). This property is specified as a Boolean.
