Database Autonomy Service (DAS) storage analysis gives you a consolidated view of how your database instance is consuming storage. Use it to monitor current usage, project how many days remain before storage is exhausted, identify the tables and databases consuming the most space, review fragment rates, and detect storage anomalies — including anomaly diagnosis results of a tablespace — all from a single page.
Limitations
Storage analysis supports up to 20,000 tables per database instance.
