> 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
> MATCH_RECOGNIZE (
> MEASURES
> A.id AS aid,
> B.id AS bid,
> C.id AS cid
> PATTERN (A B C)
> DEFINE
> A AS A.name = 'a',
> B AS B.name = 'b',
> C AS C.name = 'c'
> ) AS T
> {code}
