Use the SVL_S3LOG view to get details about Amazon Redshift Spectrum queries at the segment and node slice level.
SVL_S3LOG 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_S3LOG only contains queries run on main provisioned clusters. It doesn't contain queries run on concurrency scaling clusters or on serverless namespaces. To access explain plans for queries run on both main clusters, concurrency scaling clusters, and serverless namespaces, we recommend that you use the SYS monitoring view SYS_EXTERNAL_QUERY_DETAIL . The data in the SYS monitoring view is formatted to be easier to use and understand.
