Hi:
Does kylin support count(a particular column) now?
that is, count will skip rows which the particular column value is null.
In our test, I found it is not supported currently(kylin-1.5.2),
and I found that agg->aggCalls->arglist is null in
OLAPAggregateRule::convert when I submmit sql like:
select dt, count(xxx) from test_table group by dt;
The information about the particular column is lost in kylin, so I
want to know why?
Since I found count(xxx) is support in calcite:
