this article is generally about how to control the database logs in size by time values.
Your Vidispine API instance in Vidinet logs transactional events into four different log streams: Auditlog, Joblog, Transferlog, and Changelog. These log streams will be purged automatically in the Vidispine API instances created after 25 October 2018, but not before this date. Because of this, a database can (if not) properly managed - grow to an unnecessarily large size.
