------------------------------------
Summary: Test UnsafeRow nested struct/map round-trip for nanos
timestamps
Key: SPARK-58739
URL: https://issues.apache.org/jira/browse/SPARK-58739
Project: Spark
Issue Type: Task
Components: Spark Core
Affects Versions: 4.3.0
Reporter: Stevo Mitric
Nanos timestamp values in nested UnsafeRow structures (StructType fields and
MapType values) are implemented but untested — only top-level columns and array
elements have coverage. Add UnsafeProjection round-trip tests (codegen +
interpreted) for struct fields containing nanos (NTZ + LTZ, incl. null fields
and a nanos field beside a StringType) and map values containing nanos
(nullable NTZ with interior null; non-nullable LTZ). Test-only; no production
change.
