> Currently memory allocations in the C++ implementation are all internal / self-contained, but in practice the array builders will need to integrate with some other memory allocator / tracker.
> I'll define a basic abstract memory pool interface and add an example default implementation (with a resizable arrow::Buffer subclass that requests memory from the pool) with all memory managed internally.
