> The root cause is that there is no implementation for float/doube in
`get_creator` function in `be/src/olap/predicate_creator.h`. `get_creator` will
return default value nullptr and cause create_predicate core in the following
code.

Yes, but what confuses me is why the create_predicate of type double was not
implemented before? In other words, the double type was not pushed down to the
storage layer before because of any pitfalls?
