### Describe the usage question you have. Please include as many useful
details as possible.
TLDR: How can I trigger static initialization of the arrow C++ library?
Context:
Using apache arrow in a c++ application running on large multi NUMA
machines. The application does have its own heap framework (delegating actual
allocation to je_malloc/OS heaps) to prevent/minimize cross NUMA access. We
would like to be able to trigger all allocations needed for static variables on
a specific heap.
Example:
Is there a general way to trigger all allocations needed for static
variables like the ones below?
```
#define TYPE_FACTORY(NAME, KLASS) \
const std::shared_ptr<DataType>& NAME() { \?
static std::shared_ptr<DataType> result = std::make_shared<KLASS>(); \
return result; \
}
TYPE_FACTORY(null, NullType)
TYPE_FACTORY(boolean, BooleanType)
TYPE_FACTORY(int8, Int8Type)
TYPE_FACTORY(uint8, UInt8Type)
TYPE_FACTORY(int16, Int16Type)
TYPE_FACTORY(uint16, UInt16Type)
TYPE_FACTORY(int32, Int32Type)
TYPE_FACTORY(uint32, UInt32Type)
TYPE_FACTORY(int64, Int64Type)
TYPE_FACTORY(uint64, UInt64Type)
TYPE_FACTORY(float16, HalfFloatType)
TYPE_FACTORY(float32, FloatType)
TYPE_FACTORY(float64, DoubleType)
TYPE_FACTORY(utf8, StringType)
TYPE_FACTORY(large_utf8, LargeStringType)
TYPE_FACTORY(binary, BinaryType)
TYPE_FACTORY(large_binary, LargeBinaryType)
TYPE_FACTORY(date64, Date64Type)
TYPE_FACTORY(date32, Date32Type)
```
