There is a work in progress PR here
https://github.com/apache/camel/pull/3948
> Support topic patterns in Pulsar when subscribing
> -------------------------------------------------
>
> Key: CAMEL-15231
> URL: https://issues.apache.org/jira/browse/CAMEL-15231
> Project: Camel
> Issue Type: Wish
> Components: camel-pulsar
> Affects Versions: 3.4.0
> Reporter: Scott Anderson
> Priority: Major
> Fix For: 3.5.0
>
>
> Pulsar supports a fantastic feature that is very common to Pulsar users. That
> is subscribing to a pattern of topics defined by a regular expression.
> // Subscribe to all topics in a namespacePattern allTopicsInNamespace =
> Pattern.compile("persistent://public/default/.*");{ Consumer<byte[]>
> allTopicsConsumer = pulsarClient.newConsumer()
> .topicsPattern(allTopicsInNamespace)
> .subscriptionName("subscription-1")
> .subscribe();
> The Pulsar component in camel doesn't seem to support this important use
> case. I'm wondering if someone familiar with the Camel Pulsar component could
> estimate the level of effort for a change like this. I'm not familiar enough
> with the project to even pinpoint where a change like this should go.}}
