Maximum number of unconfirmed messages that will be sent at each redelivery burst (burst frequency is half of the redelivery interval). If there's a lot of unconfirmed messages (e.g. if the destination is not available for a long time), this helps prevent an overwhelming amount of messages to be sent at once. The default value can be configure with the 'akka.persistence.at-least-once-delivery.redelivery-burst-limit' configuration key. This method can be overridden by implementation classes to return non-default values.
