[GitHub] [pulsar] nicoloboschi opened a new issue, #16089: [Doc] Improve pulsar-perf transaction example

nicoloboschi opened a new issue, #16089:
URL: https://github.com/apache/pulsar/issues/16089

   ### What issue do you find in Pulsar docs?
   
   When using pulsar-perf transaction is not trivial to understand how you can make it working because the consume topic needs to contains enough messages to consume and the formula is:
   message to write before the command = --numSubscriptions * --numMessage-perTransaction-consume 
   
   
   ### What is your suggestion?
   
   I suggest to prepend the pulsar-perf produce command before the example and to better explain how the tool works
   Currently there's a info box but it's not very clear, a working example is far better for a user.
   
   It could be something like that:
   
   *Transactions*
   
   The transction tool will consume from the `--topics-c` topics and it will produce a message to `--topics-p` in the same transaction. Note that the tool expects the `--topics-c` topics contains at least `--numSubscriptions * --numMessage-perTransaction-consume` messages.
   
   Prepare the topic:
   `bin/pulsar-perf produce -m 50 --exit-on-failure -t 1  myConsumerTopic`
   
   Command:
   `bin/pulsar-perf transaction --topics-c myConsumerTopic --topics-p MyproduceTopic -threads 1 -ntxn 50 -ss testSub  -nmp 1 -nmc 1`
   
   ### Do you have any references?
   
   https://pulsar.apache.org/docs/next/performance-pulsar-perf/#transactions
   
   ### Would you like to fix this issue?
   
   not now
   
   ### Note
   
   - [X] I have researched my question.
