…he#44102) Problem Summary: the _batching_block is same as block which is used for output. and maybe different with input block in some column about nullable type. so if sink this will cause nullable type not equal as origin. ``` Status VRowDistribution::generate_rows_distribution( vectorized::Block& input_block, std::shared_ptr<vectorized::Block>& block, int64_t& filtered_rows, bool& has_filtered_rows, std::vector<RowPartTabletIds>& row_part_tablet_ids, int64_t& rows_stat_val) ....... // batching block rows which need new partitions. deal together at finish. if (!_batching_block) [[unlikely]] { std::unique_ptr<Block> tmp_block = block->create_same_struct_block(0); _batching_block = MutableBlock::create_unique(std::move(*tmp_block)); } ``` ``` void OlapTableBlockConvertor::_convert_to_dest_desc_block(doris::vectorized::Block* block) { for (int i = 0; i < _output_tuple_desc->slots().size() && i < block->columns(); ++i) { SlotDescriptor* desc = _output_tuple_desc->slots()[i]; if (desc->is_nullable() != block->get_by_position(i).type->is_nullable()) { if (desc->is_nullable()) { block->get_by_position(i).type = vectorized::make_nullable(block->get_by_position(i).type); block->get_by_position(i).column = vectorized::make_nullable(block->get_by_position(i).column); } else { block->get_by_position(i).type = assert_cast<const vectorized::DataTypeNullable&>( *block->get_by_position(i).type) .get_nested_type(); block->get_by_position(i).column = assert_cast<const vectorized::ColumnNullable&>( *block->get_by_position(i).column) .get_nested_column_ptr(); } } } } ```
