@matheuszych I suggest adding a new database update file/class for hotfixes in the ILIAS versions 10 and 11, and a new regular database update step file/class for ILIAS 12/trunk. |

See: https://mantis.ilias.de/view.php?id=42356 The standalone `ilBackgroundTasksDB80` class only added a single bucket index. It is removed in favour of `ilBackgroundTasksDBHotfixes10`, whose first step adds the composite `(user_id, state)` bucket index plus `bucket_id` indexes on `il_bt_task` and `il_bt_value_to_task`. The second step cleans orphaned rows, fixes dangling root/current task pointers, and creates matching InnoDB foreign keys (cascade or set-null) across the background-task tables where the engine allows it. `ilBackgroundTasksSetupAgent` delegates install objectives to the update collection (config storage plus these steps) and points metrics collection at the hotfix class.

The ILIAS 8.0 background-task migration only indexed
il_bt_bucketbyuser_id. Typical lookups filter by bucket state and join tasks or stored values viabucket_id, which stayed unindexed.step_1now replaces that index with(user_id, state)onil_bt_bucketand addsbucket_idindexes onil_bt_taskandil_bt_value_to_task./cc @thojou
