flavor​

could be ie. "spark"

use_content_defined_chunking​

requires pyarrow>=21.0.0, ignored otherwise

supports_dictionary_encoding​

When False, constant columns (like _dlt_load_id) will use regular arrays instead of dictionary-encoded arrays. Set to False for destinations using ADBC drivers that don't support dictionary types (e.g., MSSQL).

arrow_concat_promote_options​

PyArrow concat_tables promote_options for Arrow table concatenation. "none" (default) requires identical schemas and enables zero-copy concat. "default" promotes within type families (e.g. int32 to int64). "permissive" promotes across families (e.g. int64 to double).
