First recap from Trino Fest 2024

Cole and Manfred chat a bit about Trino Fest last week, mentioning that all videos are now available, and a blog post with slides and more material is coming as well.

Impression from Trino Contributor Congregation

Manfred and Dain lead the discussions in the congregation. We are excited about a lot of the follow ups for the project and increased collaboration and innovation.

Guest Patrick Pichler

PowerBI overview

Power BI is an interactive data visualization software product suite developed by Microsoft with a primary focus on business intelligence. We talk about the different available products and features, and their usage in the community.

Trino client support options for Power BI

Typically, Power BI relies on ODBC drivers for connecting to specific data sources. Since there is no open source Trino ODBC driver however, Patrick and other clever developers have created a Power BI client that connects to Trino directly via the client REST API - the PowerBITrinoConnector. We discuss the details and limitation of both approaches, look at the source code, and learn about import and direct query modes.

Demo

Patrick showcases how to install and use the connector in his demo of Trino and Power BI.
