candlerb opened a new issue #5554: pulsar-admin topics delete with multiple topics
URL: https://github.com/apache/pulsar/issues/5554
 
 
   **Is your feature request related to a problem? Please describe.**
   To clean up after running test suite, I have a bunch of old topics that need deleting.
   
   ```
   $ ../../bin/pulsar-admin topics list public/default
   "persistent://public/default/my-python-test-producer-deduplication-1572861915.695249"
   "persistent://public/default/partitioned_topic_name_test-partition-1"
   "persistent://public/default/partitioned_topic_name_test-partition-2"
   "persistent://public/default/my-v2-topic-producer-consumer"
   "persistent://public/default/partitioned_topic_name_test-partition-0"
   "persistent://public/default/my-avro-python-topic"
   ... etc
   ```
   
   **Describe the solution you'd like**
   Option 1: Allow topic wildcard matches, like subscription wildcards
   
   ```
   $ ../../bin/pulsar-admin topics delete 'my-python-topic-*'
   10:11:46.858 [AsyncHttpClient-5-1] WARN  org.apache.pulsar.client.admin.internal.BaseResource - [http://localhost:8080/admin/v2/persistent/public/default/my-python-topic-*?force=false] Failed to perform http delete request: javax.ws.rs.NotFoundException: HTTP 404 Not Found
   ```
   
   Option 2: Allow `topics delete` to accept more than one topic on the command line.  Currently it enforces a single topic:
   
   ```
   $ ../../bin/pulsar-admin topics delete "persistent://public/default/my-python-topics-consumer-1-partition-0"  "persistent://public/default/my-python-topics-consumer-3-partition-2" "persistent://public/default/my-python-topics-consumer-3-partition-3"
   Need to provide just 1 parameter
   ```
   
   **Describe alternatives you've considered**
   Very slow workaround (since pulsar-admin has 4-5 second Java startup overhead per invocation):
   
   ```
   ../../bin/pulsar-admin topics list public/default | sed 's/"//g' |
     while read a; do echo "$a"; ../../bin/pulsar-admin topics delete "$a"; done
   ```
   
   **Additional context**
   N/A
