@Dandandan offered an interesting option trying the Primitive Dictionary Builder in https://github.com/apache/arrow-datafusion/issues/5472#issuecomment-1454123133 It would be interesting to test it out, as I understand the idea is not to use `PrimitiveDictionaryBuilder` directly but build a similar more lightweight structure? Could elaborate a bit how do you see it? Another question for Ballista, for distributed COUNT DISTINCT to get final aggregated result, they should use the same structure right ? -- This is an automated message from the Apache Git Service.
