  • I really enjoyed most of this and I think it’s a good video for a dark winter morning when inspiration is at a low

• https://tc19.tableau.com/learn/sessions/how-data-literacy-saved-world-modern-day-lessons-code-breakers-world-war-ii

  • Not super applicable to our work but a really interesting talk

• https://tc19.tableau.com/learn/sessions/zen-master-you-did-what-your-data-deep-dive-imputing-and-densifying-data (ways to Impute - assign a value to something, Pad - add rows or columns, Densify - Tableau-specific type of padding)

  • ~25min: Creating a scaffold, ZN()

  • ~35-40min: Dates

  • ~50min: Nesting table calcs

  • Workbook Design (reduce filters; how many marks do you need? aggregation levels; avoid massive crosstabs as a default; optimize the popular content first)

  • Database design (Index relevant fields; Fewer columns is better; parameterizing data source filters; materialized tables)

  • Optimize extracts (localize your data; only keep data you care about; reduce load on live databases; hide row or fields; materialize your dates)

  • Server topology (1 vizQL / 4 cores)

  • VM resource allocation (Reserve CPU & memory)

  • AntiVirus software (Excluding Tableau & Windows directories, & scheduling can help. Link to whitepaper)

• https://tc19.tableau.com/learn/sessions/performance-best-practices-hyper-extracts

  • The language of hyper is SQL (I have enough notes that I’ll probably want to rewatch this one)

  • This was a nice implementation of a set of differently-aggregated KPIs, so as to aim high-level simple numbers at executives/leadership, and into-the-weeds displays at the boots-on-the-ground people. I think it’s worth watching for ideas about how we could simplify our views.
