## Note per l'utilizzo
<a name="SYS_AUTOMATIC_OPTIMIZATION-usage-notes"></a>

La colonna compute\$1type sarà vuota per i cluster serverless perché non distinguiamo le risorse di calcolo primarie da quelle su scala primaria. Le risorse di elaborazione del cluster serverless vengono misurate in base all'utilizzo delle Redshift Processing Units ().

La seguente query mostra le ottimizzazioni automatiche eseguite sulla tabella 155259.

```
SELECT pid, trim(task_type) as task_type,
  trim(database) as database,
  trim(status) as status,
  trim(event) as event,
  event_time
from SYS_AUTOMATIC_OPTIMIZATION
WHERE object_ids like '%155259%'
AND status = 'Task completed successfully';

 task_type  |    database    |           status            |   event   |         event_time
------------+----------------+-----------------------------+-----------+----------------------------
 VacuumSort | tpcds_100g_oob | Task completed successfully | Completed | 2025-12-22 07:27:15.943018
