Kostas Kloudas commented on FLINK-6371: --------------------------------------- This is the PR that addresses it: https://github.com/apache/flink/pull/3909 > Return matched patterns as Map<String, List<T>> instead of Map<String, T> > -------------------------------------------------------------------------- > > Key: FLINK-6371 > URL: https://issues.apache.org/jira/browse/FLINK-6371 > Project: Flink > Issue Type: Bug > Components: CEP > Affects Versions: 1.3.0 > Reporter: Kostas Kloudas > Assignee: Kostas Kloudas > Fix For: 1.3.0 > > > As reported in the last comments of this PR > https://github.com/apache/flink/pull/3477#issuecomment-294306997 , currently > the {{select()/flatSelect()}} functions receive the matched patterns as maps > of the form {{Map<String, T>}}, where String is the name of the > pattern and T is the actual event. > With the introduction of quantifiers, we now may have multiple events for a > given pattern (e.g. with {{oneOrMore()}}). To accommodate > this addition, this issue proposes to transform the output format of the > matched patterns to {{Map<String, List<T>>}}. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
