JNSimba opened a new pull request, #553:

   # Proposed changes
   
   Issue Number: close #xxx
   
   ## Problem Summary:
   
   There is the following flinksql
   ```select * from table limit 10```
   
   When doris has a large data table, it will first scan all the data in the 
table, and then make a limit.
   
   Here you can push the limit down to reduce the amount of data scanned.
   
   Note that this is only partially pushed down, so the scanned data and the 
limit value may not be equal (For example, under multiple tablets, the scanned 
data will be greater than the limit value), and it will eventually rely on the 
upper-level Limit of FlinkSQL to do it
