Hi,
Just to add on top to what Fabian said.
The only community supported CEP library is the one that comes with Flink[1].
It is also used internally to support the MATCH_RECOGNIZE clause in Flink
SQL[2]. Therefore there is a both programmatic library native DSL for defining
patterns. Moreover you can use SQL. As Fabian mentioned, you can say the
library is in a maintenance mode, primarily because there is no one interested
in actively working on it.
If you use other CEP libraries that are integrated with Flink, it's probably a
better idea to reach out to the maintainers of said libraries.
Lastly, I am not aware of any comparisons of CEP libraries/extensions that work
with Flink. I am afraid you have to do the feature comparison yourself. I think
the documentation for community supported library is a good start for it.
Best,
Dawid

Hi Dipanjan,
I am afraid there are no foreseeable efforts planned but if you find a nice
addition, you can start a discussion in the community about this feature.
Best, Fabian

Hi Fabian,
Understood but is there any plan to grow the flink CEP and build a
friendly DSL around flink CEP by any chance.

Hi Dipanjan,
Unfortunately, I have no experience with Siddhi but I am not aware of any
official joined efforts between Flink and Siddhi. I can imagine that not all
Siddhi CEP expressions are compatible with Flink’s CEP. At the moment there is
also no active development for Flink’s CEP.
I think to get a better understanding what the caveats are of the third party
solution you have to directly reach out to the maintainers.
Best, Fabian

Hi ,
I am currently using Siddhi CEP with flink , but the flink-siddhi library
has limited support for flnk versions and i will either need to fix the library
or get tied to a fix version of Flink to use th library.
I am looking at Flink CEP as an option , and also came across a Flink CEP
DSL library (https://github.com/phil3k3/flink-cep-dsl) , but i am not sure
about the acceptance for the same by the Flink community and DEV. Also is Flink
CEP supporting the Siddhi CEP constructs and is rich on the same aspect.
Please let me know the same , so that i can take a cautious decision on the
same.
Regards Dipanjan
