---------------------------------------------
Summary: Specific constructor for Decimal128Array
Key: ARROW-9798
URL: https://issues.apache.org/jira/browse/ARROW-9798
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Affects Versions: 1.0.0
Reporter: Mathieu Dutour Sikiric
I would like to create a Decimal128Array in arrow.
For the StructArray, ListArray, MapArray we have constructors taking buffers,
null_bitmap and such and the way to create arrays is clear.
However, the only constructor available for Decimal128Array is with an
ArrayData which seems strange. Why can't we have a constructor using a data
buffer and a bitmap buffer?
If that is not possible, I would be interested with code for creating a
Decimal128Array from a data and bitmap buffer.
