The correct answer is that Tableau first refreshes extract filters during an update. Extract filters are a type of filter that is applied to the data before it is brought into Tableau from a data source. This means that when an extract is created or refreshed, the extract filter helps limit the data that is included in the extract. By applying these filters first, Tableau optimizes the amount of data being processed and minimizes the load on memory and performance, ensuring that only relevant data is pulled into the Tableau environment. In contrast to extract filters, context filters are applied at a later stage and can change the context for all other filters, possibly affecting the data set size and the filters' outcomes. Data source filters are also evaluated after extract filters, thus taking a secondary role in the refresh order. Lastly, refreshing all filters at once would lead to inefficiencies and would not consider the hierarchical dependency and data volume management that Tableau incorporates during its filtering process.
