Pattern change on runtime

Hi,

I want to know, can we change the pattern on runtime?

I've read on stackoverflow "at the moment flink does not support". Does it
change?

Hi Aljoscha,

Thank you for information

Hi,

Yes, currently the pattern of a CEP operator cannot be changed. You could
manually implement this by using a ConnectedStream with a CoProcessFunction
where the first input carries events and the second input carries commands
that change the patterns that you monitor.

Best,
Aljoscha
