>                 URL: https://issues.apache.org/jira/browse/FLINK-7062

> In this JIRA, we will support the basic functionality of {{MATCH_RECOGNIZE}} 
> in Flink SQL API which includes the support of syntax {{MEASURES}}, 
> {{PATTERN}} and {{DEFINE}}. This would allow users write basic cep use cases 
> with SQL like the following example:
> {code}
> SELECT T.aid, T.bid, T.cid
> FROM MyTable
>     A.id AS aid,
>     B.id AS bid,
>     C.id AS cid
>     A AS A.name = 'a',
>     B AS B.name = 'b',
>     C AS C.name = 'c'
> ) AS T
> {code}
