> C++: Externalize memory allocations and add a MemoryPool abstract interface
> to builder classes
> ----------------------------------------------------------------------------------------------

> Key: ARROW-19
> URL: https://issues.apache.org/jira/browse/ARROW-19
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++
> Reporter: Wes McKinney
> Assignee: Wes McKinney
>
> 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.
