Wes McKinney updated ARROW-2264:
--------------------------------
Component/s: Python
> Efficiently serialize numpy arrays with dtype of unicode fixed length string
> ----------------------------------------------------------------------------
>
> Key: ARROW-2264
> URL: https://issues.apache.org/jira/browse/ARROW-2264
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Affects Versions: 0.8.0
> Reporter: Mitar
> Priority: Major
>
> Looking at the numpy array serialization code it seems that if I have a dtype
> like "<U3" this will go through custom ndarray serializer and not through an
> efficient one.
> {{Example:}}{{>>> np.array(['aaa', 'bbb'])}}
> {{array(['aaa', 'bbb'], dtype='<U3')}}
> This should be able to work, no? It has fixed offsets and memory layout.
