> Currently, there are four kinds of {{FunctionDefinition.Type}},
> {code:java}
> public enum Type {
> AGGREGATE_FUNCTION,
> SCALAR_FUNCTION,
> TABLE_FUNCTION,
> OTHER_FUNCTION
> }
> {code}
> The Type AGGREGATE_FUNCTION is used to express both AggregateFunction and TableAggregateFunction. However, due to the two kinds of the function contains different semantics. It would be nice if we can separate these two kinds of functions more clearly by introducing another type TABLE_AGGREGATE_FUNCTION.
