[GitHub] [pinot] TT1103 opened a new issue #7417: Add config to automatically generate only the dimensionsSplitOrder in star tree

[GitBox <gi...@apache.org>]

TT1103 opened a new issue #7417:
URL: https://github.com/apache/pinot/issues/7417


   Currently, we can specify enableDefaultStarTree=True, which will create a default star tree. It will automatically generate the dimensionsSplitOrder by taking the dimension columns and sorting them by cardinality in descending order. It also contains some default pre-aggregations and a maxLeafRecords. 
   
   But we can't add more pre-aggregations to the default config. 
   It would be useful if we can add a config to only generate the dimensionsSplitOrder in descending order, and be able to manually specify the other parts.
