Enum SubscriptionType 

pub enum SubscriptionType {
    Exclusive,
    Shared,
    Failover,
    KeyShared,
}

How competing consumers on one subscription share its messages.

Variants

Exclusive

One consumer holds the subscription.

A server refuses a second attach as busy, and the client retries it until OperationRetries runs out, which by default is never: a second consumer of this subscription is a service that does not start. A bound on the retries turns the wait into PulsarError::Subscribe. In process, under the test harness, the attach is refused with that error at once, so the test fails rather than hangs.

Shared

Competing consumers, round-robin. The default.

Failover

One active consumer with hot standbys.

KeyShared

Competing consumers with per-key ordering (the Partitioned capability’s transport).
