--------------------------------------
Summary: [C++] Add a Result<> returning method for for
constructing a dictionary
Key: ARROW-9049
URL: https://issues.apache.org/jira/browse/ARROW-9049
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Micah Kornfield
Assignee: Micah Kornfield
Dictionary types require a signed integer index type. Today there is a DCHECK
that this is the case in the constructor.
When reading data from an unknown source it is possible due to corruption (or
user error) that the dictionary index type is not signed. We should add a
method that checks for signedness and use that at all system boundaries to
validate input data.
