@julianhyde : I checked the issue you posted - CALCITE-3144 and I think it solves one of the two problems mentioned in this thread - of transforming a case statement to a filtered aggregator for optimized execution in some systems. But the other problem still remains, ie the following query still throws an error `SELECT COUNT(DISTINCT foo.dim1) FILTER(WHERE foo.cnt = 1), SUM(foo.cnt) FROM druid.foo` and explanation that Gian wrote above still hold according to me. Do you recall any reason for not making any changes in `AggregateExpandDistinctAggregatesRule`? -- This is an automated message from the Apache Git Service.
