Hi Is there any good scientific papers about using SQL MATCH_RECOGNIZE in Flink and CEP ?
The only one good paper about Flink and CEP that I have received was “Efficient Pattern Matching over Event Streams” (SIGMOD 2008). Its SASE+ Event Pattern Language (EPL) is best I have met. I have been told that FlinkCEP is based on this.

Hi Esa, Flink's implementation of SQL MATCH_RECOGNIZE is based on it's CEP library, i.e., they share the same implementation. Best, Fabian Am Do., 11.

Should the all sources be combined into one big table before operations with SQL CEP? Yes, you should combine them into one table/stream.

How this SQL CEP is applicable for situation where there are many sources with different type of events ? Should the all sources be combined into one big table before operations with SQL CEP?

Is it already possible to use SQL in CEP? Is there any example cases where SQL is used in CEP? BR Esa
