--------------------------------

             Summary: [C++] Slice methods should return empty arrays instead of crashing
                 Key: ARROW-10054
                 URL: https://issues.apache.org/jira/browse/ARROW-10054
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
    Affects Versions: 1.0.1
            Reporter: David Li


This crashes because of a CHECK assert. However, it's surprising to Python users who would expect an empty slice, or at least an exception.
{code:java}
>>> import pyarrow as pa
>>> table = pa.table([[1,2,3], [4,5,6]], names=["a", "b"])
>>> table.slice(4, 5)
/arrow/cpp/src/arrow/chunked_array.cc:122:  Check failed: (offset) <= (length_) Slice offset greater than array length
