[GitHub] [pulsar] nha opened a new issue #8547: java client: expose endOfTopic event listener
nha opened a new issue #8547:
URL: https://github.com/apache/pulsar/issues/8547
**Is your enhancement request related to a problem? Please describe.**
In the pulsar java client, allow registering a listener for the `endOfTopic` event that can be used when calling `.receive`-style calls without having to use a `messageListener`.
From https://pulsar.apache.org/api/client/org/apache/pulsar/client/api/ConsumerBuilder.html#messageListener-org.apache.pulsar.client.api.MessageListener-
(emphasis mine)
> When a MessageListener is set, application will receive messages through it.
> **Calls to Consumer.receive() will not be allowed.**
**Describe the solution you'd like**
Setting another listener only for `endOfTopic` events in the `ConsumerBuilder`
**Describe alternatives you've considered**
I cannot think of an alternative.
**Additional context**
https://github.com/apache/pulsar/blob/db6afd52841108b0c35f0a0bdd0759f5243d93e0/pulsar-client/src/main/java/org/apache/pulsar/client/impl/ConsumerBase.java#L141-L144

Closing following the discussion on Slack, I can use the `TopicTerminatedException` instead.
