Big Data Discovery stores project creation and usage information in its database.
When entries are added to the usage logs
When entries are deleted from the usage logs
By default, whenever you start Big Data Discovery, all entries 90 days old or older are deleted from the usage logs.
To change the age of the entries to delete, add the following setting to portal-ext.properties
:
studio.startup.log.cleanup.age=entryAgeInDays
In addition to the age-based deletions, Big Data Discovery also deletes entries associated with data sets and projects that have been deleted.
