Subject [jira] [Created] (ARROW-457) Python: Better control over memory pool
Date Fri, 06 Jan 2017 14:52:58 GMT
Uwe L. Korn created ARROW-457:
---------------------------------

             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}}.
