[GitHub] merlimat opened a new pull request #613: Reduce memory usage in producer and subscriptions maps

merlimat opened a new pull request #613: Reduce memory usage in producer and subscriptions maps
URL: https://github.com/apache/incubator-pulsar/pull/613
 
 
   ### Motivation
   
   In the topic object, we're creating a map to reference producers, subscriptions and replicators. This map is not heavily contented and in most cases it would have far less than 256 items on it. 
   
   ### Modifications
   
   Reduce the expected items from the default of 256 to 16 and use a single hash-table section instead of default of 16.
