# Which issue does this PR close? - Closes https://github.com/apache/arrow-rs/issues/8828 # Rationale for this change This PR implements row format conversion for Union types (both sparse and dense modes) in the row kernel. Union types can now be encoded into the row format for sorting and comparison ops It handles both sparse and dense union modes by encoding each row as a null sentinel byte, followed by the type id byte, and then the encoded child row data. During decoding, rows are grouped by their type id and routed to the appropriate child converter -- This is an automated message from the Apache Git Service.
