This is the initial public release of the VizQL Data Service (VDS). VDS provides a way for you to access your data outside of a Tableau visualization (viz).
With a viz, you perform operations like dragging a pill to rows or columns. This achieves two things: It fetches data from the data source, and it creates a visualization of that data. VDS allows you to perform a fetch of the data without the need for any visualization.
There are substantial changes from the previous developer preview release. If you used the developer preview release, please note the following changes.
QuantitativeNumericalFilter
and QuantitativeDateFilter
, which are specific to their types.Filter
object has changed. Now each ‘Filter
requires a FilterField
.Filter
excludes null values. Use an includeNulls
field with a quantitative filter.SPECIAL
filter type, and now a quantitative filter has new options of ONLY_NULL
, and ONLY_NON_NULL
, which you can use to filter appropriately.RelativeDateFilter
. The LASTN
NEXTN

to specify relative ranges. The other date range types are shortcuts. For more information, see the Relative date filters.MatchFilter
type to do string matching.October 2024
