One work-around is to concat the two columns into a single string, e.g. `select distinctcounthll(concat(id, date, ',')) from myTable`. The performance could be sub-optimal because the dictionary/type-based optimization cannot be applied. To optimize the performance, one solution is to combine multiple values from different columns into a `byte[]` then feed into the hll/thetasketch. This should give better performance than representing numbers using strings -- This is an automated message from the Apache Git Service.
