Public preview: Azure Cosmos DB V2 Connector for Power BI

The new Azure Cosmos DB connector V2 for Power BI now allows you to import data into your dashboards using the DirectQuery mode, in addition to the previously available Import mode.

The DirectQuery mode in the V2 connector is helpful in scenarios where Azure Cosmos DB container data volume is large enough to be imported into Power BI cache via Import mode. It’s also helpful in scenarios where real-time reporting with the latest ingested data is a requirement. This feature can help you reduce data movement between Azure Cosmos DB and Power BI, with filtering and aggregations being pushed down. It is also helpful in user scenarios where real-time reporting with the latest ingested data is a requirement. Direct Query also has performance optimizations related to query pushdown and data serialization.
