Hi [~weijie], there's some discussion about this in ARROW-15289 - please feel
free to chime in there!
> array supply mutable interface to allow the user to do in place update
> -----------------------------------------------------------------------

> Key: ARROW-15319
> URL: https://issues.apache.org/jira/browse/ARROW-15319
> Project: Apache Arrow
> Issue Type: Wish
> Components: C++
> Reporter: Weijie Tong
> Priority: Major
>
> Now ,arrow's c++ Array interface does not allow user to do in place update,
> it's a read only interface. If we want to update an existing array ,we need
> to re-create one by ArrayBuilder.
> But some cases like we want to do sort an arrow array or do additional filter
> to an exsiting filter(i.e. a BooleanArray), we could do a in place update to
> save the additional allocating, ( for example ,we supply a
> mutable_raw_values() interface to NumericArray).
> So want to know the community advice about the possible to add such mutable
> interace to the Array interface.
