Hi Esa,

Flink's implementation of SQL MATCH_RECOGNIZE is based on it's CEP library, i.e., they share the same implementation.

Hi

 

Is SQL CEP based (old) FlinkCEP at all and are SQL CEP and FlinkCEP completely separate ?

Should the all sources be combined into one big table before operations with SQL CEP?

 

Yes, you should combine them into one table/stream.

Hi

 

Thank you for the information. 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?

Hi

 

What is the situation of FlinkCEP and SQL?

 

Is it already possible to use SQL in CEP?

 

Is there any example cases where SQL is used in CEP?
