The [[https://cloud.invantive.com/roller|Roller Power BI connector]] is based on the Invantive UniversalSQL driver for Roller, completed by a high-performance OData connector which works straight on Power BI without any add-on. The OData protocol is always version 4, independent whether the backing platform uses OData, SOAP or another protocol. For technical users there are command-line editions of Invantive Data Hub running on iOS, Android, Windows, MacOS and Linux. Invantive Data Hub is also often used for enterprise server applications such as ETL. High-volume replication of data taken from the Roller API into traditional databases such as SQL Server (on-premises and Azure), MySQL, PostgreSQL and Oracle is possible using [[https://cloud.invantive.com/data-replicator/|Invantive Data Replicator]]. Invantive Data Replicator automatically creates and maintains Roller datawarehouses, possibly in combination with data from over 75 other (cloud) platforms. Invantive Data Replicator supports data volumes up to over 1 TB and over 5.000 companies. The on-premise edition of Invantive Bridge offers an Roller ADO.net provider. Finally, online web apps can be build for Roller using App Online of [[https://cloud.invantive.com/roller|Invantive Cloud]]. Monitor API Calls When a query or DML-statement has been executed on Invantive UniversalSQL a developer can evaluate the actual calls made to Roller using a query on sessionios@DataDictionary. As an alternative, extensive request and response logging can be enabled by setting log-native-calls-to-disk to true. In the %USERPROFILE%\Invantive\NativeLog folder Invantive UniversalSQL will create log files per Roller request and response. ## Specifications The SQL driver for Roller does not support partitioning.
