Overview

Data prioritization automatically kicks in whenever you use a Group By clause.

Within each group outlined by your Group By clause, the query executor would implicitly:

  • Sub-group the data further by their Provider and their Source Type;
  • Keep only data from the sub-group that has the highest Source Type priority, or the highest Provider priority when multiple sub-group exists for the same Source Type.

Data prioritization works only in a Group By context.

If both the Provider and Source Type Source Columns are present in the Group By clause, the implicit Data Prioritization behaviour would be disabled.

​
Previewing the prioritization effect

You can experiment and preview the effect of prioritization using the Query API.

By specifying a list of provider slugs in config.provider_priority_overrides, you instruct the query executor to treat these providers as the highest priority — above the team provider priority — specifically in this query invocation.

​
Managing Provider Priorities

You can manage the provider priorities for each summary type through the Data Priority section of the Vital Dashboard.

A larger number indicates a higher priority.

​
Source Type Priorities

We use pre-assigned, non-configurable Source Type priorities that follow the general expectation of data reliability.
