# SourceMysqlInvalidCDCPositionBehaviorAdvanced

Determines whether Airbyte should fail or re-sync data in case of an stale/invalid cursor value into the WAL. If 'Fail sync' is chosen, a user will have to manually reset the connection before being able to continue syncing data. If 'Re-sync data' is chosen, Airbyte will automatically trigger a refresh but could lead to higher cloud costs and data loss.
