| `tolerateStateMismatch` | Allows the connector to drop records "earlier" than the current offset stored AFTER_PROCESSING (e.g. if offset 5 is sent, and offset 250 was the last recorded offset) | `"false"` |
119-
| `ignorePartitionsWhenBatching` | Will ignore partition when collecting messages for insert (though only if exactlyOnce is `false`). Performance Note: The more connector tasks, the fewer kafka partitions assigned per task - this can mean diminishing returns. | `"false"` |
