Summary
We began this chapter with a discussion of the performance-recording dashboard. This was important because many of the subsequent exercises utilized the performance-recording dashboard to examine underlying queries. Next, we discussed hardware and on-the-fly techniques, where the intent was to communicate hardware considerations for good Tableau performance and, in the absence of optimal hardware, techniques for squeezing the best possible performance out of any computer.
Then we covered working with data sources, including joining, blending, and efficiently working with data sources. This was followed by a discussion on generating and using extracts as efficiently as possible. By focusing on data sources for these three sections, we learned best practices and what to avoid when working with either remote datasets or extracts. The next sections explored performance implications for various types of filters and calculations. Lastly, we looked at additional performance considerations...
