[GitHub] [pulsar] massakam opened a new pull request #6851: [broker] Enable users to set subscription expiration time for each namespace

[GitBox <gi...@apache.org>]

massakam opened a new pull request #6851:
URL: https://github.com/apache/pulsar/pull/6851


   ### Motivation
   
   We can automatically delete inactive subscriptions by setting `subscriptionExpirationTimeMinutes` in broker.conf to a value greater than 0.
   ```sh
   # How long to delete inactive subscriptions from last consuming
   # When it is 0, inactive subscriptions are not deleted automatically
   subscriptionExpirationTimeMinutes=0
   ```
   
   However, since this setting value applies to all topics, we have to set it to 0 if there is even one topic whose subscriptions should not be deleted.
   
   ### Modifications
   
   Enable users to set a subscription expiration time for each namespace. This value overrides `subscriptionExpirationTimeMinutes` in broker.conf.
   ```sh
   $ ./bin/pulsar-admin namespaces set-subscription-expiration-time --time 60 tenant1/ns1
   $ ./bin/pulsar-admin namespaces get-subscription-expiration-time tenant1/ns1
   
   60
   ```
