Issue

  • DDMTemplateVersion table has many records and we are not using it.
  • In addition, it can cause some minor performance issues.
  • Is it possible to clean up that table?

Environment

  • Liferay DXP 7.4+

Resolution

NOTE: Be sure to take a backup of your database prior to making any changes. Always test the changes in a lower environment before making changes in production.

Making manual changes to the database is not recommended, and should be carefully assessed based on your own business needs and risk factors. Any such operation is performed at the sole discretion of your own team.

  • It is an old implementation that is not used anywhere in the UI.
  • If you are not using that versioning through custom code, then you can use the attached script to delete them. It deletes all records from DDMTemplateVersion except those corresponding to the latest version.
