Description

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.}}
