   @sijie Now I switch to blocking read and  then everything is fine. I want to prevent blocking for a  long time, I call `lastShardTxId = dlm.getLastTxId();` when I reeach the lastShardTxId, I will sleep for a while 100ms and then call `dlm.getLastTxId();` to check if there 's new log entry to read.
   
   My question is: Is this a good practice or not?
