congestion_failure_threshold specifies whether to add an OBServer node to the blocklist.
If the number of failures of an OBServer node exceeds the specified value during the period specified by congestion_fail_window, OceanBase Database Proxy (ODP) will add this OBServer node to the blocklist. If you specify a value smaller than 0, all OBServer nodes in the blocklist will be removed from the blocklist. For more information about the congestion_fail_window parameter, see congestion_fail_window.
