Proposed changes
In auto partition, new streams may be created after some sinks closed.
But the initial
use_cntof those streams are stillnum_local_sinks,which causes
use_cntcannot reach 0 andCLOSE_LOADwill never be sent.This PR fixes this problem by removing
use_cntfrom individual streams.Sinks will now rely on the
use_cntin eachLoadStreamMapto determine whether this is the last sink.Only the last sink will handle the close_load, close_wait and commit_info.
Further comments
If this is a relatively large or complex change, kick off the discussion at dev@doris.apache.org by explaining why you chose the solution you did and what alternatives you considered, etc...
