Aliaksei Sandryhaila commented on PARQUET-542:
----------------------------------------------
Tentatively:
- introduce a MemoryPool interface with Allocate() and Free() methods;
- implement a default class that uses std::malloc() and std::free();
- have Buffer and its descendants use a specified MemoryPool class.
If you want to have compatibility with Impala, MemPool (that was ported from
Impala) can be made a descendant of the MemoryPool interface.
> Support memory allocation from external memory
