   > @weizuo93 You are right. I am wrong. This PR could go ahead. (But store 
some load job meta in FE and store some load job meta in BE, which seems not 
very good)
   
   @kangkaisen 
   Thanks for your comment. There is code overlap between this PR and PR 
#5452(https://github.com/apache/incubator-doris/pull/5452). After discussion 
with Mingyu Chen, we first push forward PR #5452. About storing stream load 
meta in BE, it's a tradeoff. If BE reports the stream load result to FE  when 
each stream load job finished, it may result in too much stress for FE RPC. So 
the stream load results are temporarily stored on BE and then sent to FE by 
batch. After finished data sending, stream load meta will be removed from BE 
soon. Do you have any better idea?
