# Public Properties
| Property | Description |
|---|---|
| behaviors (opens new window) | yii\base\Behavior (opens new window) – List of behaviors attached to this component. |
| db | craft\db\Connection, array (opens new window), string (opens new window) – The database connection to use |
| deleteAllTrashed | boolean (opens new window) – Whether hardDelete() should delete all soft-deleted rows, rather than just the ones that were deleted long enough ago to be ready for hard-deletion per the config4:softDeleteDuration (opens new window) config setting. |
| probability | integer (opens new window) – The probability (parts per million) that garbage collection (GC) should be performed on a request. |
# db
- Type
- craft\db\Connection, array (opens new window), string (opens new window)
- Default value
'db'- Since
- 4.0.0

# deleteAllTrashed
- Type
- boolean (opens new window)
- Default value
false
Whether hardDelete() should delete all soft-deleted rows, rather than just the ones that were deleted long enough ago to be ready for hard-deletion per the config4:softDeleteDuration (opens new window) config setting.

# probability
- Type
- integer (opens new window)
- Default value
10
The probability (parts per million) that garbage collection (GC) should be performed on a request. Defaults to 10, meaning 0.001% chance.
This number should be between 0 and 1000000. A value 0 means no GC will be performed at all unless forced.
