Significance of "optiontype" in customfieldoption table in Jira Database


I have been working on multi-checkbox custom field plugin development (Jira Server) and I have reached a stage where I would like to understand a significance of “optiontype” column in customfieldoption table in Jira database scheme. As this column is always found “NULL” in its table but I want to know that if we could store some data in it and later we could use it at some where in plugin development.

Your support will be highly appreciated.


I realize this is a necropost so I’m sorry for that but: Under entitymodel.xml within the Jira source code, this is labeled as deprecated:

<!-- @deprecated as of 3.1 -->
        <field name="type" col-name="optiontype" type="short-varchar"/>
