Hi Li,
I've faced this issue before, and I ended up using a generic ArrayBuilder,
for example:
```cpp
auto type = int32();
std::vector> scalars = {MakeScalar(1),
MakeScalar(2)};
ARROW_ASSIGN_OR_RAISE(std::unique_ptr builder,
MakeBuilder(type));
Hi,
I find myself in need of a function to turn a vector of Scalar to an Array
of the same datatype. The data type is known at the runtime. e.g.
shared_ptr concat_scalars(vector values.
shared_ptr type);
I wonder if I need to use sth like Scalar::Accept(ScalarVisitor*) or is
there an
