Configuring Durable Interest in Keys
When a durable client disconnects, its servers keep queuing messages for selected keys. The client indicates which keys by registering durable interest for those keys.
Configuring Durable Client Reconnection
You can configure the durable native client to obtain an approximate count of pending events upon durable client reconnection. Based on the returned number, you can determine whether to proceed and receive the pending events or whether to close the cache.
