SVL_S3LIST
Use the SVL_S3LIST view to get details about Amazon Redshift Spectrum queries at the segment level.
SVL_S3LIST is visible to all users. Superusers can see all rows; regular users can see only their own data. For more information, see Visibility of data in system tables and views.
Note
SVL_S3LIST only contains queries run on main clusters. It doesn't contain queries run on concurrency scaling clusters. To access queries run on both main and concurrency scaling clusters, we recommend that you use the SYS monitoring view SYS_EXTERNAL_QUERY_DETAIL .
