Hi, devs. 

I'd like to start a discussion about FLIP-302: Support TRUNCATE TABLE statement 
[1]. 

The TRUNCATE TABLE statement is a SQL command that allows users to quickly and 
efficiently delete all rows from a table without dropping the table itself. 
This statement is commonly used in data warehouse, where large data sets are 
frequently loaded and unloaded from tables. 
So, this FLIP is meant to support TRUNCATE TABLE statement. M ore exactly, this 
FLIP will bring Flink the TRUNCATE TABLE syntax and an interface with which the 
coresponding connectors can implement their own logic for truncating table. 

Looking forwards to your feedback.
