-----------------------------------
Summary: [C++][Compute] Filter out nulls by default
Key: ARROW-8235
URL: https://issues.apache.org/jira/browse/ARROW-8235
Project: Apache Arrow
Issue Type: Improvement
Components: C++ - Compute
Affects Versions: 0.16.0
Reporter: Ben Kietzman
Assignee: Ben Kietzman
Fix For: 0.17.0
The filter kernel currently emits null when a slot in the selection mask is
null. For compatibility with Kleene logic systems like SQL, this behavior
should be configurable. Provide an option enumeration:
{code}
struct FilterOptions {
enum NullSelectionBehavior {
/// null slots in the selection mask will drop the filtered value
DROP,
/// null slots in the selection mask will keep the filtered value
KEEP,
/// null slots in the selection mask will replace the filtered value with
null
EMIT_NULL,
} null_selection_behavior;
};
{code}
