Hi Esa, Flink 1.7 will come with an initial support for MATCH_RECOGNIZE clause which integrates Flink CEP library with SQL.
You can find the documentation for that feature in the SNAPSHOT docs: https://ci.apache.org/projects/flink/flink-docs-master/dev/table/streaming/match_recognize.html Best, Dawid On 28/11/2018 10:06, Esa Heikkinen wrote: > > Hi > > > > What is the situation of SQL/CEP ? > > > > Flink 1.7 is coming soon, but what about SQL/CEP ? > > > > Whether it already exists documentation of SQL/CEP ? > > Event better if there were scientific papers about it ? > > > > BR Esa > > > > *From:*Timo Walther <twal...@apache.org> > *Sent:* Tuesday, August 7, 2018 4:52 PM > *To:* user@flink.apache.org > *Subject:* Re: FlinkCEP and scientific papers ? > > > > Hi Esa, > > the SQL/CEP integration might be part of Flink 1.7.
