**How can you run reports in PowerBI when your tables are too large for import mode, but direct mode queries are too slow?**

With Power BI aggregate tables and dual mode you can run most of your workload on small, aggregated data in import mode, while allowing user to drill into the full tables in direct query if needed.

Rescheduled: Navigating Large Data in PowerBI 

Online event

We are pleased to be able to offer you a Deep Dive Session Level 400 with Alberto Ferrari as part of our regional group meeting of the RG Rheinland.

As we unfortunately have to limit the places for this event to 9 participants, you should register early.

**Understanding composite models in Power BI - Level 400**

Provided that you already know what a composite model is, do you also know what the technical details to produce fast and efficient composite models are? In this very technical session we extend the knowledge beyond the basics, understanding the technical details of composite models, so to build efficient systems.
We see in detail good and bad practices.

When working with Azure Cosmos DB, Andrew Evans was looking for a way to have reusable scripts for common actions performed with their team's data. Andrew discovered the Azure Cosmos Python SDK and successfully developed basic Python scripts that could be utilized in their daily tasks. With the SDK at their disposal, Andrew now has the capability to create new scripts for tasks such as bug fixes and other maintenance activities, and can easily reference them for future use.

**Description**
Administrators and analysts often struggle with the storage and maintenance of reporting and analytics data. Traditional rowstore tables do not scale well when data is measured in billions of rows.

Columnstore indexes provide a speedy and convenient way to store OLAP data within SQL Server. Compression allows the data to be much smaller than other storage methods, allowing for faster reads. Column metadata provides the tools needed for SQL Server to be able to service queries over massive data sets quickly and efficiently.

The basics of columnstore indexes allow an administrator to improve the performance of analytics, but there is much more to learn! Understanding the internals of columnstore indexes allows querying to be even more efficient.

Columnstore indexes have evolved greatly since their introduction in SQL Server 2012. This presentation explores this feature in SQL Server 2017 and SQL Server 2019 and how its newest features can turbo-charge your analytics workloads!
