Uwe L. Korn created ARROW-1964:
----------------------------------
Summary: Python: Expose Builder classes
Key: ARROW-1964
URL: https://issues.apache.org/jira/browse/ARROW-1964
Project: Apache Arrow
Issue Type: New Feature
Components: Python
Reporter: Uwe L. Korn
Fix For: 1.0.0
Having the builder classes available from Python would be very helpful.
Currently a construction of an Arrow array always need to have a Python list or
numpy array as intermediate. As the builder in combination with jemalloc are
very efficient in building up non-chunked memory, it would be nice to directly
use them in certain cases.
