study freeze

To prevent changes to a study, use biograph vdb study freeze. Frozen studies may still be exported, but the add, delete, revert, and filter commands can no longer be used.

$ biograph vdb study freeze my_study
Study 'my_study' frozen

$ biograph vdb study delete my_study
The study 'my_study' is frozen and cannot be altered.

$ biograph vdb study filter my_study --exclude "GT = '1/1'"
The study 'my_study' is frozen and cannot be altered.

Note that changes are only prevented when using vdb commands. The underlying S3 and Athena data can still be changed or deleted by anyone with sufficient privileges.

To allow changes again, use study unfreeze.
