The following query shows stream and topic data for specific queries.

```
select query_id,mv_name::varchar,external_schema_name::varchar,stream_name::varchar,sum(scanned_rows) total_records,
sum(scanned_bytes) total_bytes from sys_stream_scan_states where query in (5401180,8601939) group by 1,2,3,4;
