let's say I give field data a fix value of memory in config, what will happen if it is not enough to load whole necessary data? will it throw exception to client or will it load necessary data arbitary?

@warkolm no bother to answer it. I have already found it out.  
paste the answer below in case anybody get interest:  
If the estimated query size is larger than the limit, the circuit breaker is  
tripped and the query will be aborted and return an exception. This happens  
before data is loaded, which means that you won’t hit an  
OutOfMemoryException.
