When a client connects to a MQTT broker using a persistent session,
the message broker saves all subscriptions. When the client
disconnects, the message broker stores unacknowledged QoS 1 messages
and new QoS 1 messages published to topics to which the client is
subscribed. When the client reconnects to the persistent session,
all subscriptions are reinstated and all stored messages are sent to
the client. Setting this flag to 0 allows the client to create a
persistent session.
