The read code is in the `FileColumnIterator::next_batch(size_t* n, vectorized::MutableColumnPtr& dst, bool* has_null)` method. When `null` is read from the page, `dst->insert_data(nullptr, 0);` is called (the `insert_default` method of ColumnDict will be called). If non-null, call `_page.data_decoder->next_batch();` (will call the `insert_many_dict_data` method of ColumnDict, the dictionary will be built on the first call) -- This is an automated message from the Apache Git Service.
