Hello,

We have a query regarding our use case.

Use Case:
We need to send descriptive alerts from Flink operators triggered based on 
certain criteria.

Queries:

  1.  Is there any mechanism provided by Flink, which can be used to send these 
alerts?
  2.  We considered using the Async operators, and send the alerts using the 
async REST HTTP call. If the answer to query 1 is No, then is this the 
recommended way, considering there is possibility of back-pressure in case of 
high load?

Thanks,
Pratham
