   > There are two main issues
   > 
   > 1. all query requests need to send an RPC to Master FE, which is too much 
overhead.
   > 2. Limiter is not set in the right place. For example, for query, it 
should be handled at the place where the query plan is finally sent to BE. For 
load, the frequency of transactions should be limited.
   
   Yes, that seems to have too much RPC. I have rewrote the feature with 
statistic sychronize based on bdbje. Because I think it's fine to use bdbje to 
store some temperory statistics, and there is too much work to develop a 
middleware myself.
   
   Please review this patch, thanks for your time!
