Convenience function checking if communication recovery is allowed.

Communication recovery is only allowed in load-balancing configurations. It is enabled by setting delayed-updates-limit to a value greater than 0.

Returns: true if communication recovery is enabled, false otherwise.

uint32_t isc::ha::HAConfig::getDelayedUpdatesLimit ( ) const

inline

Returns the maximum number of lease updates which can be held unsent in the communication-recovery state.

If the server is in the communication-recovery state it is unable to send lease updates to the partner. Instead it keeps lease updates, hoping to send them when the communication is resumed. This value designates a limit of how many such updates can be held. If this number is exceeded the server continues to respond to the clients but will have to go through regular lease database synchronization when the communication is resumed.

Returns: Limit of the lease backlog size in communication-recovery.
