[GitHub] [pulsar] wangjialing218 opened a new issue, #18149: [Bug] Partitioned DLQ topic with topic name contains -partition- may cause broker crash
wangjialing218 opened a new issue, #18149:
URL: https://github.com/apache/pulsar/issues/18149
### Search before asking
- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.
### Version
Version: Pulsar 2.9.3
### Minimal reproduce step
broker set config as follow:
```
{
allowAutoTopicCreation: true,
allowAutoTopicCreationType: "partitioned",
defaultNumPartitions: 1
}
```
Client consume a partitioned topic with default DLQ policy.
When client trigger DLQ topic auto creation, a topic with name like `persistent://public/default/test-partition-0-sub-DLQ` will be created.
Call admin api to get subscriptions or create subsction for this DLQ topic.
### What did you expect to see?
Broker works fine.
### What did you see instead?
Owner broker of the DLQ topic will hande the get subscriptions request. Broker send another nested get subscriptions request to itself in a very high frequency.
Broker become very slow to handle other request, and after about 1 or 2 hours broker disconnected from zookeeper and restart.
The DLQ topic will unload to another broker and cause another broker meet same problem.
### Anything else?
For the partitioned DLQ topic with topic name contains `-partition-`, in `internalGetSubscriptions` https://github.com/apache/pulsar/blob/639393d43e36bd26112866a00b0cff98fae9d0ac/pulsar-broker/src/main/java/org/apache/pulsar/broker/admin/impl/PersistentTopicsBase.java#L1140
Since partitions = 1, another getSubscriptions request with same topic name will send to the broker itself. https://github.com/apache/pulsar/blob/639393d43e36bd26112866a00b0cff98fae9d0ac/pulsar-broker/src/main/java/org/apache/pulsar/broker/admin/impl/PersistentTopicsBase.java#L1166
