NestedRow.getVector still threw the "Unsupported type: VectorType" stub left by apache#7204, so a primary-key table with a ROW<..., VECTOR> column failed at flush when the format writer read the nested row. Mirror BinaryRow.getVector / BinaryArray.getVector (apache#9773) with MemorySegmentUtils.readVectorData. Generated-by: Claude Code

Purpose
fix #9861
NestedRow.getVectorstill threwIllegalArgumentException("Unsupported type: VectorType"), so a primary-key table with aROW<..., VECTOR>column failed at flush: the write buffer holdsBinaryRow, and the Parquet/Avro writer reads the nested row viaBinaryRow.getRow()→NestedRow.getVector().MemorySegmentUtils.readVectorData, mirroringBinaryRow.getVectorandBinaryArray.getVector;BinaryWriter.writeVectoralready writes the nested slot, so the layout is unchanged.BinaryArrayandNestedRow; [common] Support VECTOR elements in InternalArray accessors #9773 fixedBinaryArray; this fixes the last one.Tests
NestedRowTest#testNestedRowWithVector: round-trip ofROW<INT, ROW<INT, VECTOR(3, FLOAT)>>, null vector field,InternalRow.createFieldGetter(VECTOR), and the multi-segment case. Fails with the stub exception without the fix.mvn -pl paimon-common clean install(JDK 11): BUILD SUCCESS, 0 failures (checkstyle, spotless, enforcer included);NestedRowTest4/4.
