Currently, I wanna take Shark’s (Spark SQL) DDL and DML as an reference to design/implement SQLE’s DDL and DML. However, I cannot find its DDL and DML. I can only find several SQLs in Shark paper.

Shark’s language is Hive QL. HQL’s DDL and DML can be found at
An good overview can be found at Hive and Shark SQL and Rich Analytics at Scale by Amir H. Payberah.
