Review Comment:
@xiedeyantu No, according to your writing above, all aggregate functions
will execute the logic of your method, but you only described the sum aggregate
function in the jira case, which seems a bit strange. If some functions of
ClickHouse are not supported by Calcite, you at least need to record JavaDoc to
explain it.
