Review Comment:
   @sumitagrawl @devmadhuu I am surely missing something here. Correct me if I 
am wrong, we are doing a continue here as per this statement which will skip 
the null value here. So all I am asking is when we are initializing 
cacheCreatedKeyIter can we skip null values? The key would be still there in 
the cacheKeyMap. It will make this code much simpler.
