public class SqlReplaceTableAs extends org.apache.calcite.sql.SqlCreate implements ExtendedSqlNode
SqlNode to describe the [CREATE OR] REPLACE TABLE AS (RTAS) syntax. The RTAS would create a pipeline to compute the result of the given query and create or replace the derived table.

Notes: REPLACE TABLE AS: the derived table must exist. CREATE OR REPLACE TABLE AS: create the derived table if it does not exist, otherwise replace it.

Example: 


 CREATE TABLE base_table (
     id BIGINT,
     name STRING,
     time TIMESTAMP,
     PRIMARY KEY(id)
 ) WITH (
     ‘connector’ = ‘kafka’,
     ‘connector.starting-offset’: ‘12345’,
     ‘format’ =  ‘json’
 )

 CREATE OR REPLACE TABLE derived_table
 WITH (
   'connector' = 'jdbc',
   'url' = 'http://localhost:10000',
   'table-name' = 'syncedTable'
 )
 AS SELECT * FROM base_table;
