--------------------------------

I am very interested in the CEP part. And my team is exploring this feature and 
try to integrate it into our products, and I also want to contribute to this 
feature. However I find that many tasks are not in the correct status and many 
pull requests have not been reviewed for a long time. Is there anyone can help 
to manage these Jira issues ?

> Flink's CEP library is a great library for complex event processing, more and 
> more customers are expressing their interests in it. But it also has some 
> limitations that users usually have to write a lot of code even for a very 
> simple pattern match use case as it currently only supports the Java API.
> CEP DSLs and SQLs strongly resemble each other. CEP's additional features 
> compared to SQL boil down to pattern detection. So It will be awesome to 
> consolidate CEP and SQL. It makes SQL more powerful to support more usage 
> scenario. And it gives users the ability to easily and quickly to build CEP 
> applications.
> The FLIP can be found here:
> https://cwiki.apache.org/confluence/display/FLINK/FLIP-20%3A+Integration+of+SQL+and+CEP
> This is an umbrella issue for the FLIP. We should wait for Calcite 1.13 to 
> start this work.
