> Support reusing same variable in Pattern
> ----------------------------------------
>
> Key: FLINK-10588
> URL: https://issues.apache.org/jira/browse/FLINK-10588
> Project: Flink
> Issue Type: Sub-task
> Components: Library / CEP, Table SQL / API
> Affects Versions: 1.7.0
> Reporter: Dawid Wysakowicz
> Priority: Major
>
> One should be able to use the same variable multiple times in a pattern. So
> we should allow patterns like (A B A).
> CEP library enforces unique names for patterns. A simple workaround to
> generate artificial unique names won't work in this case because having
> multiple patterns with same name puts additional constraints on AFTER MATCH
> SKIP as it skips to LAST/FIRST element of elements assigned to both instances.
