I try to use the same SQL(Flink: 1.14) as streaming in batch to calculate every minute distinct user count, in order to repair the wrong result in streaming, but it give errors: `DISTINCT aggregates are currently not supported.`
I wonder why DISTINCT aggregates is not supported? And will it be supported ?
PS: I find that it still not support in Flink: 1.15-SNAPSHOTS, using window TVF.
