Contributor guide
Research direction
Start by locating where Spark ORC configuration is translated into ClickHouse settings, using the two configuration names as search terms. Verify the mapping with the repository's existing configuration or integration tests, if present; done means the Spark threshold is applied as output_format_orc_dictionary_key_size_threshold.
