In-Database Processing in Tableau Prep (Snowflake)

In-database processing in Tableau Prep for Snowflake is powerful, but watch those credits.

  • In-database processing lets you run Prep operations directly in your Snowflake database, dramatically speeding up flows on large datasets
  • This capability already existed for other databases (such as Databricks) and now extends to Snowflake, bringing the big hyperscalers into play
  • Be careful with credit consumption, as pushing operations across your entire dataset on a large warehouse can burn through Snowflake credits
  • Sampling settings in Tableau Prep still matter and, if misconfigured, can cause serious problems, so pay close attention to them

Tableau Prep now lets you push operations directly to your Snowflake database, rather than processing everything locally. For large datasets, this is a game-changer in terms of speed. But a word of caution - if you’re running this against your full dataset without proper sampling, you could burn through Snowflake credits fast. Make sure your sampling settings are dialled in.
