BackendServiceConnectionTrackingPolicy_ConnectionPersistenceOnUnhealthyBackends class final

Specifies connection persistence when backends are unhealthy. The default value is DEFAULT_FOR_PROTOCOL.

If set to DEFAULT_FOR_PROTOCOL, the existing connections persist on unhealthy backends only for connection-oriented protocols (TCP and SCTP) and only if the Tracking Mode isPER_CONNECTION (default tracking mode) or the Session Affinity is configured for 5-tuple. They do not persist forUDP.

If set to NEVER_PERSIST, after a backend becomes unhealthy, the existing connections on the unhealthy backend are never persisted on the unhealthy backend. They are always diverted to newly selected healthy backends (unless all backends are unhealthy).

If set to ALWAYS_PERSIST, existing connections always persist on unhealthy backends regardless of protocol and session affinity. It is generally not recommended to use this mode overriding the default.

For more details, see Connection Persistence for Network Load Balancing and Connection Persistence for Internal TCP/UDP Load Balancing.
