[jira] [Commented] (ARROW-9401) [C++/Python] Support necessary functionality to have an Arrow-string type in pandas

    [ https://issues.apache.org/jira/browse/ARROW-9401?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17562114#comment-17562114 ] 

F. H. commented on ARROW-9401:
------------------------------

So there is now the `String[pyarrow]` type in pandas.

Can we use this automatically when converting a pyarrow table to pandas?

Currently I still get `str` back when converting pyarrow -> pandas...

> This should serve as an umbrella issue for the needed functionality to have an Apache Arrow backed string type in {{pandas}}. In addition to the string kernels (ARROW-555), we probably need to implement some more support functionality to efficiently the {{pandas}} interfaces.
> Some of these functions are already present in {{fletcher}} but a native string type in {{pandas}} should not have a hard dependency on {{numba}}.
