Description
While executing a query with joins against Cosmos DB from TDV Studio, you may run into duplicating data for columns that are from a join or you may observe missing columns in the result when functions like IsNull are used in the query :
The cause of the issue is currently the QueryPassthrough option is not supported by CosmosDB
