merlimat opened a new pull request #2854: Fixed ZLib decompression in C++ client
URL: https://github.com/apache/pulsar/pull/2854
 
 
   ### Motivation
   
   The ZLib method `uncompress()` is not able to process data that was compressed from Pulsar Java producer with ZLib. 
   
   This is due to the the initialization settings that are used inside the `uncompress()` functions and that are different from how ZLib is used within the JDK. 
   
   This causes C++ (and derivatives) consumers to drop messages that were compressed by Java producer. A Java consumer is able to correctly decompress both.
   
   ### Modifications
   
    * Fixed decompression in C++ to be able to inflate both zstream terminations
    * Added option in C++ perf producer to compress messages
