This is particularly important for Azure where there is no MyISAM support in their MariaDB cloud product. Like mysqldumper does, a view can satisfy the requirement like a table, without constraints. The views in frm files are text form and don't have column limits. Thanks Thomas Casteleyn for the suggestion.
