The configuration data is stored on every node but is updated on the master

only. After each update, the master distributes the data to the other nodes.

Currently the data storage format is pickle as yaml was initially not


  		





  32
  
  
    
available, then we used it but it was a memory-eating slow beast, so


  		





  33
  
  
    
we reverted to pickle using custom Unpicklers.


  		





  
  29
  
    
Currently, the data storage format is JSON. YAML was slow and consuming too


  		





  
  30
  
    
much memory.
