Weijie Tong created ARROW-15319:
-----------------------------------
Summary: 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
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.
