bundle.stage_row_field calls meta.field_id_literal_value() once per field on each row on the stage. This requires a query to the table for every field, which is making bundle.commit() run very slow. Optimize this to instead issue only one query per row_id in bundle.stage_row. Probably using row_to_json().
