Description

Hi !

We've been developping an embedded analytics module based on cube, with an extensive use of drill down. While it's working fine for most queries, it's not yet supported for queries with a date range comparison (and we plan to use it quite a lot)

For instance, the graph below is made from a comparison with a compare date range. image (1)

Would it be possible to extend the coverage of drill down ?

Many thanks in advance for your support on this

Research direction
Investigate the existing drill down implementation in Cube's core query engine, focusing on how it works for regular queries and how compareDateRange is handled. Examine the SQL generation code for drill down and date range comparisons, likely in the Rust source or the JavaScript query builder. Check if there are any existing tests or discussions about this feature in the repository. The goal is to understand the gaps and propose an extension to support drill down when compareDateRange is used.
