2. Power BI for large databases
Agenda
PowerBI - Imported mode for large databases
Power BI - Live Connection for large databases
Power BI - Direct Query with large database
Power BI - Big Data Sets

3. Survey Among these tables which is the biggest dataset ?
One table with 5,000 records
One table with 500,000 record
One table with 5 Million records
One table with 5 Billion records
A dataset is a collection of data that you import or connect to.

4. VertiPaq In-memory Technology (xVelocity)
VertiPaq engine: the in-memory columnar database that stores and hosts your model. Available in Power Pivot, Power BI, Analysis Services Tabular, SQL Server ColumnStore Indexes.
VertiPaq Analyzer reports the memory consumption of the data model. s/vertipaq-analyzer/
VertiPaq engine: the in-memory columnar database that stores and hosts your model.

5. Power BI Service
Security

8. Different users access same database through various reporting tools, and work with different subsets of data based on their identity/role

10. Up to 100GB and refresh up to every 30 min, Starting $5K for 50 users 2.5GB for P1 Capacity Node.

15. Azure Analysis Services scale up to 400GB

16. PowerBI Modes Comparison
DirectQuery Mode
Imported Mode
Live Connection
Data Size after compression
(database, table, cardinality)
Very large dataset
1 GB <= PBI Free
10 GB <= PBI Pro
10GB > PBI Premium
Up to 400GB SSAS
Data Source Types
Limited
Many
Number of Data Source
1 (only)
Power Query Transformations
Limited (to simple)
Not Limited (can do complex)
No Power Query
DAX (Data Analysis Expressions)
As of June 2018:
Power BI Premium - Incremental refresh in preview.
Azure Analysis Services scale up to 400GB.

17. Big Data Sets with Power BI in HDInsight
Imported Mode using Microsoft Hive ODBC Driver - data refreshes with this method can often be slow as a Hive job will be executed on your cluster before transferring the data
Imported Mode - HDInsight into Power BI is by connecting to flat files in either Blob or the Data Lake Store
Direct Query - Power BI can then use Spark SQL to interactively query the tables in Power BI's DirectQuery mode.
Direct Query - process your data in your cluster, but write the resulting curated and/or aggregated data to tables in Azure SQL DB (or Azure SQL Data Warehouse).
