Database Autonomy Service (DAS) provides the storage analysis feature, which gives you a complete picture of how your database instance uses storage. Use it to check current storage consumption, estimate how long remaining storage will last, and inspect tablespace-level detail including fragmentation and anomaly diagnosis results.
The storage analysis feature can analyze up to 20,000 tables.
