The Power BI plan comparison and limits table at the URL below states maximum total data sizes limit (1GB free or 10GB paid) and maximum streaming throughput limits (10k rows per hour free or 1 million rows per hour paid). https://powerbi.com/dashboards/pricing/ Specific questions are: (1) How are the data size limits measured? Is this the size of the raw data or the size of the compressed tabular model? The page isn't specific about what the size limit applies to. (2) Do the throughput limits apply ONLY when using the Azure Stream Analytics preview connector or do they also apply when using the REST API? e.g. if using the free Power BI tier (and assuming I don't go over the 1GB total size limit), is the maximum number of rows I can submit per hour limited to 10k (e.g. 2 calls within an hour of 5k rows each or 4 calls of 2.5k rows each, etc)?
