Miscellaneous
This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.
| Property | Description |
| BatchSize | Specifies the maximum number of rows included in each batch submitted during batch operations. To submit the entire batch as a single request, set BatchSize to 0 . |
| ConnectionLifeTime | Specifies the maximum lifetime of a connection in seconds. When the specified time elapses, the provider closes the connection. |
| ConnectOnOpen | Specifies whether the provider establishes a connection to Microsoft Power BI XMLA immediately upon opening the connection. Set ConnectOnOpen to True if immediate connectivity verification is necessary. |
| CustomHeaders | Specifies additional HTTP headers to append to the request headers created from other properties, such as ContentType and From. Use this property to customize requests for specialized or nonstandard APIs. |
| ExposeMemberKeys | Enable this property to convert each level into a measure, which is a numeric value that supports calculations like summing, averaging, and other aggregations. By default, levels remain as String types, so they do not support direct calculations. |
| ExpressionInDescription | Enable this property to append measure expressions in the descriptions of measure columns. By default, the provider includes only remarks in measure column descriptions. |
| ExtraProperties | Specifies additional properties to include in each MDX request sent to Microsoft Power BI XMLA. Use this property to customize the PropertiesList of the XMLA request when UseMDX is enabled. |
| MaxRows | Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY. |
| Other | Specifies additional hidden properties for specific use cases., to be used only when our Support team advises it, to address specific issues. See Remarks for details. |
| PoolIdleTimeout | Specifies the maximum idle time, in seconds, that a connection can remain in the pool before being closed. Requires UseConnectionPooling=True. |
| PoolMaxSize | Specifies the maximum number of connections allowed in the connection pool. |
| PoolMinSize | Specifies the minimum number of connections to be maintained in the connection pool at all times. |
| PoolWaitTime | Specifies the maximum number of seconds a connection request waits for an available connection in the pool. If the wait exceeds this time, an error is returned. |
| ResponseRowLimit | Specifies the maximum number of response rows allowed before triggering an error. Use 0 to remove the limit entirely. This property helps prevent performance issues caused by large queries. |
| RTK | Specifies the runtime key for licensing the provider. If unset or invalid, the provider defaults to the standard licensing method. This property is only required in environments where the standard licensing method is unsupported or requires a runtime key. |
| ShowHiddenEntities | Enable this property to include hidden dimensions, measures, and levels in query results. By default, the provider excludes entities marked as hidden. |
| SplitMeasures | Enable this property to split the Measures table into individual tables and distribute measures into their respective dimension tables. |
| SplitMeasuresOn | Specifies the priority for organizing measures into tables when SplitMeasures is enabled. Provide a comma-delimited list of attributes to determine the sorting order. |
| Timeout | Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. |
| UseConnectionPooling | Enables the connection pooling feature, which allows the provider to reuse existing connections instead of creating new ones for each request. |
| UseMDX | Enable this property to pass MDX queries directly to Microsoft Power BI XMLA. When disabled, the provider translates SQL-92 queries into operations on the modeled views. |
| UserDefinedViews | Specifies a filepath to a JSON configuration file that defines custom views. The provider automatically detects and uses the views specified in this file. |
| Workspace | Specifies the Premium Power BI workspace(s) to connect to, using a comma-separated list of workspace names. |
