Delete Custom Object API processing speed issue

Hello, I have an inquiry regarding the development regarding DELETE of custom object data.

Currently, we have established Custom Object No. 462 (Integrated DB_Account_History) and are using it in various ways. Approximately 100,000 to 200,000 data per day will be loaded on the corresponding CO, and it is expected that too much data will be accumulated even after a month, so we are going to develop a logic to delete CustomObject Data collectively as of 7 days.

Now I will tell you about my inquiry.

Delete custom object data: /api/rest/2.0/data/customObject/{parentId}/instance/{id}

We implemented logic to delete custom object data using the API above.
