Relationship Columns and Power BI DirectQuery Mode

Published 2024-03-11 by Kevin Feasel

Chris Webb builds a relationship:

Many Power BI connectors for relational databases, such as the SQL Server connector, have an advanced option to control whether relationship columns are returned or not. By default this option is on. Returning these relationship columns adds a small overhead to the time taken to open a connection to a data source and so, for Power BI DirectQuery semantic models, turning this option off can improve report performance slightly.

Read on to learn what these relationship columns are and how you can remove them. Chris also provides a first-order approach to how you can estimate the performance pain involved with including these.

Analyzing TDS 8.0 Handshake Packets with Wireshark

Published 2024-03-11 by Kevin Feasel

Matt Changchien fires up the packet capture tool:

The main difference between TLS1.2 and TLS1.3 is that TLS 1.3 reduces the number of round trips from two to one during the handshake phase, making it faster and more secure than TLS 1.2. The server hello packet containing server certificate is encrypted and one Round Trip Time (1-RTT) resumption is discontinued, and replaced with 0-RTT resumption based on client key share. Added security of TLS 1.3 comes from discontinuing certain cyphers and algorithms. (TLS 1.3 support – SQL Server | Microsoft Learn)

Click through to see what the differences look like between TLS 1.2 and TLS 1.3, as well as the specific example of Azure SQL Database.
