ALTER on a large table through methods of deletion, field type change, or field length increase, times out by UI quota rule and gets cancelled on the back end leaving orphaned metadata behind

KB Summary by Now Assist

Description

When trying to ALTER a large table though methods such as deletion, field type change, or field length increase, transactions times out and gets cancelled on the back end.

Steps to Reproduce

  1. Create a new column directly on the [task] table (the table needs to have over 2 million records for larger ALTER).
    • Creating a column will not time out, this has already been tested
  2. From the UI, delete a column or change the Field Type of the new column created on the [task] table.

Expected results: The transactions should complete even if it goes over the 298 seconds.

Actual results: The Transaction times out and gets cancelled from the back end causing orphaned metadata (which connects to PRB1315639 - When ALTERS are cancelled it leaves behind orphaned metadata)

Workaround

Please consult KB0547328 - Creating or altering a field on a large table from the UI can be canceled by "UI Transactions" Quota Rule
