Gunakan SYS\$1AUTOMATIC\$1OPTIMIZATION untuk melihat detail tugas yang dijalankan Amazon Redshift untuk pengoptimalan otomatis, juga dikenal sebagai otonom. Untuk informasi selengkapnya tentang pengoptimalan otomatis, lihat[Optimalisasi basis data otomatis](c_autonomics.md).

SYS\$1AUTOMATIC\$1OPTIMIZATION hanya terlihat oleh pengguna super. Untuk informasi selengkapnya, lihat [Visibilitas data dalam tabel dan tampilan sistem](cm_chap_system-tables.md#c_visibility-of-data).

## Catatan penggunaan
<a name="SYS_AUTOMATIC_OPTIMIZATION-usage-notes"></a>

Kolom compute\$1type akan kosong untuk cluster tanpa server karena kita tidak membedakan sumber daya komputasi skala primer atau primer. Sumber daya komputasi klaster tanpa server diukur dengan penggunaan Redshift Processing Units (). RPUs Untuk informasi selengkapnya, lihat [Kapasitas komputasi untuk Amazon Redshift](https://docs.aws.amazon.com/redshift/latest/mgmt/serverless-capacity.html) Tanpa Server.

## Contoh

Kueri berikut menampilkan pengoptimalan otomatis yang dilakukan pada tabel 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
