Auto-scaling policies can be configured in two ways: when you create an instance or after you create a GeminiDB (for Cassandra) instance. If storage autoscaling is enabled, GeminiDB (for Cassandra) instances can automatically scale up after the storage space of the instance reaches a threshold.
If auto-scaling has been triggered, the increased allocated storage space can be found on the 'Basic Information' page in the 'Storage Space' section.
Further information can be found in the GeminiDB(for Cassandra) area of the Help Centers.
