[GitHub] [pulsar] ocelot93 opened a new issue #10972: `subscriptionExpirationTimeMinutes` option is not working
ocelot93 opened a new issue #10972:
URL: https://github.com/apache/pulsar/issues/10972
**Describe the bug**
Default value for `subscriptionExpirationTimeMinutes` is `0`, which means that inactive subscriptions are not being deleted automatically. Setting this value to `1` (for example) means that subscription has to be deleted `1` minute after last consumed message (or after the time set in `subscriptionExpiryCheckIntervalInMinutes` setting)
**To Reproduce**
Steps to reproduce the behavior:
1. Spin up Pulsar in docker container
2. Create a topic (e.g. `testTopic`)
3. Set `subscriptionExpirationTimeMinutes` to 1 (either with `set-subscription-expiration-time` command of pulsar-admin CLI or with Pulsar Admin REST API)
4. Subscribe for this topic and produce any message
5. Wait until subscription is deleted automatically. It will persist forever regardless of new messages absence
6. Active subscriptions presence can be checked with REST API request - `{pulsar address}/admin/v2/non-persistent/public/default/testTopic/stats` - it will produce a response like this:
```

}
],
"isDurable": false,
"isReplicated": false,
"msgDropRate": 0.0
}
},
"replication": {},
"msgDropRate": 0.0
}
```
**Expected behavior**
Information about a subscription has to be deleted after subscription expiration time has been reached. New exclusive consumers should be able to use the same subscription name afterwards.
**Screenshots**
No screenshots.

`subscriptionExpirationTimeMinutes` > 0 means how long to delete inactive subscriptions from last consuming. If the consumer still connected to the topic without consuming messages, the subscription is still active, and it won't be auto deleted.
@ocelot93 Between step 4 and 5, did you close the consumer?
