Fields

topic: String

subscription: String

sub_type: i32

consumer_id: u64

request_id: u64

consumer_name: Option<String>

priority_level: Option<i32>

durable: Option<bool>

Signal wether the subscription should be backed by a durable cursor or not

start_message_id: Option<MessageIdData>

If specified, the subscription will position the cursor markd-delete position on the particular message id and will send messages from that point

metadata: Vec<KeyValue>

read_compacted: Option<bool>

schema: Option<Schema>

initial_position: Option<i32>

Signal whether the subscription will initialize on latest or not – earliest

replicate_subscription_state: Option<bool>

Mark the subscription as “replicated”. Pulsar will make sure to periodically sync the state of replicated subscriptions across different clusters (when using geo-replication).

force_topic_creation: Option<bool>

If true, the subscribe operation will cause a topic to be created if it does not exist already (and if topic auto-creation is allowed by broker. If false, the subscribe operation will fail if the topic does not exist.

start_message_rollback_duration_sec: Option<u64>

If specified, the subscription will reset cursor’s position back to specified seconds and will send messages from that point

key_shared_meta: Option<KeySharedMeta>
