   > sorry, The variable name is `forward_to_master`, `set forward_to_master = 
true`
   
   The variable does not have any effect. I only have one FE master. 
Reproducing the issue is easy. Simply create a table, insert some data, and 
immediately execute "show data". Initially, the data may appear empty, but 
after waiting for an uncertain amount of time, the data will eventually be 
displayed. The waiting time can vary, sometimes it may not require any wait, 
while other times it may take more than 10 seconds or longer.
