---------------------------------------------
Summary: [C++] HashTable/MemoTable should use Buffer(s)/Builder(s)
for heap data
Key: ARROW-5527
URL: https://issues.apache.org/jira/browse/ARROW-5527
Project: Apache Arrow
Issue Type: Improvement
Reporter: Francois Saint-Jacques
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).
