-------------------------------------
Summary: [C++] Create a caching memory pool implementation
Key: ARROW-3406
URL: https://issues.apache.org/jira/browse/ARROW-3406
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Affects Versions: 0.11.0
Reporter: Antoine Pitrou
A caching memory pool implementation would be able to recycle freed memory
blocks instead of returning them to the system immediately. Two different
policies may be chosen:
* either an unbounded cache
* or a size-limited cache, perhaps with some kind of LRU mechanism
Such a feature might help e.g. for CSV parsing, when reading and parsing data
into temporary memory buffers.
