---------------------------------
Summary: Python: Better control over memory pool
Key: ARROW-457
URL: https://issues.apache.org/jira/browse/ARROW-457
Project: Apache Arrow
Issue Type: Improvement
Components: Python
Reporter: Uwe L. Korn
Currently we have a separate {{PyArrowMemoryPool}} implemented in
{{src/pyarrrow/common.cc/h}}. Instead we should use the default memory pool
from Arrow-C++ as often as possible.
Furthermore the user should be able to configure which MemoryPool is actually
used in the cases where one can select a custom MemoryPool. For ease of use,
there should also be a way to switch the default MemoryPool in Python to a
user-selected one, e.g. the {{jemalloc::MemoryPool}}.
