This is a protected member of the abstract SubscriptionClient class. Abstract classes are not meant to be inherited, so protected members should be ignored.
You can use to fetch multiple messages from the server in the same round-trip. This can be useful in scenarios that need lower latency for receiving existing messages from a queue or subscription. Prefetch can also improve throughput depending upon the scenarios as the number of round-trips to the server are reduced.
Prefetch is disabled by default. You can enable it by using this property on the client. You must set before receiving the first message.
