[GitHub] [pinot] Jackie-Jiang opened a new issue, #8863: Allow transform function as the dimension in the star-tree
Jackie-Jiang opened a new issue, #8863:
URL: https://github.com/apache/pinot/issues/8863
Currently in order to build a star-tree on top of a transform function, user needs to follow these steps:
1. Create a derived column (single-value dictionary encoded) from the transform
2. Create star-tree on top of the derived column
3. Query derived column in order to use star-tree
We should be able to simplify these steps and allow transform function as the dimension in star-tree. Internally we can follow the same steps and generate a hidden column for the derived column and build star-tree on top of it. At query time, we may re-write the query to query the hidden column
