Subscription Store

Courier library uses Subscription Store for maintaining the current subscriptions and pending unsubscribe requests.

Currently there are two implementations of SubscriptionStore provided by Courier library.

PersistableSubscriptionStore

In this implementation, the current subscriptions are maintained in-memory and pending unsubscribe requests are maintained in shared preferences. When client reconnects, subscription packets are sent again and pending unsubscribe packets are also sent, if present.

InMemorySubscriptionStore

In this implementation, the current subscriptions are maintained in-memory and no pending unsubscribe requests are maintained. When client reconnects, subscription packets are sent again.
