   Complex Event Processing (CEP) SQL Realization  is a new feature. Use statement :
   ```sql 
   SELECT [ ALL | DISTINCT ]
   { * | projectItem [, projectItem ]* }
   FROM tableExpression
   [MATCH_RECOGNIZE (
   [PARTITION BY {partitionItem [, partitionItem]*}]
   [ORDER BY {orderItem [, orderItem]*}]
   [MEASURES {measureItem AS col [, measureItem AS col]*}]
   [ONE ROW PER MATCH|ALL ROWS PER MATCH|ONE ROW PER MATCH WITH TIMEOUT ROWS|ALL ROWS PER
MATCH WITH TIMEOUT ROWS]
   [AFTER MATCH SKIP]
   PATTERN (patternVariable[quantifier] [ patternVariable[quantifier]]*) WITHIN intervalExpression
   DEFINE {patternVariable AS patternDefinationExpression [, patternVariable AS patternDefinationExpression]*}
   )];
   
   ```
   I cann't create new pull request, sorry
