public class RowsAndColumnsSerializer
extends com.fasterxml.jackson.databind.ser.std.StdSerializer<RowsAndColumns>

Serializer for RowsAndColumns by converting the instance to WireTransferable. See the javadoc on WireTransferable for information on the serde contract. There is a legacy serialization format for FrameRowsAndColumns that serializes the signature object followed by frame bytes. This legacy format can be enabled via WireTransferableContext.useLegacyFrameSerialization() for compatibility during rolling updates. Once all servers have been upgraded, this can be set to false.
