>                 Key: ARROW-5527
>                 URL: https://issues.apache.org/jira/browse/ARROW-5527
>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: C++
>            Reporter: Francois Saint-Jacques
>            Priority: Major
>
> The current implementation uses `std::vector` and `std::string` with unbounded size. The refactor would take a memory pool in the constructor for buffer management and would get rid of vectors.
> This will have the side effect of propagating Status to some calls (notably insert due to Upsize failing to resize).
