About the project usage logs

Big Data Discovery stores project creation and usage information in its database.

When entries are added to the usage logs

Entries are added when users:
  • Log in to Big Data Discovery
  • Navigate to a project
  • Navigate to a different page in a project
  • Create a data set from the Data Source Library
  • Create a project

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.
