In order to make the follow query work:
select max(A), lastwithtime(A, array(C0, C1)) from table group by B
There are two things we need pay attention to:
1. We need add the data type for C0,C1 since when creating the aggregation
function, there is no data type for each column;
2. C0 and C1 should have the same data type
Here is my proposal:
select max(A), lastwithtime(A, 'dataType', C0, C1) from table group by B
MV should work for this use case
