[GitHub] [pulsar] merlimat opened a new pull request #8331: [C++] Client back-pressure is done on batches rather than number of messages

merlimat opened a new pull request #8331:
URL: https://github.com/apache/pulsar/pull/8331


   ### Motivation
   
   C++ client can end up using a huge amount of memory under certain conditions: 
    * Batching enabled
    * Number of messages per batch high
    * Several partitions
   
   ### Modifications
   
   We need to use messages rather than batches for the sizing of the pending messages queue and back-pressure. Same as how it happens in Java and Go client implementations. Otherwise, the batching size becomes a multiplier of these settings.
