Significance of "optiontype" in customfieldoption table in Jira Database

Hello,

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.

Thanks,
Nisarg

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"/>
