Aliaksei Sandryhaila commented on PARQUET-542:
----------------------------------------------
As a part of this feature, we should either implement a custom STL allocator or
replace std::vector with a custom DataArray class that can use an external
memory pool. I strongly support the latter option, for multiple reasons,
including
- ensure that the array capacity cannot be increased implicitly, by adding new
elements,
- ensure that array size and capacity change are handled explicitly and
precisely to the specified parameter.
> Support memory allocation from external memory
