> [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
> Priority: Minor
> Labels: query-engine
>
> 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.
