You can probably check the size of the materialized view since they occupy physical space on disk.   Periodic checking should show increase in size

Hi Laurenz,

Thanks for responding. Most of the time I am seeing wait event, same view if I create directly in source DB, it’s quick.

Thanks & Regards,

Occasional occurrences could be normal; in that case, it is
probably the query that takes a long time.
