Hi Sharif,
You could not catch exceptions globally.
For exceptions that can be explicitly ignored for your business, you need
to add a try-catch in the operators.
For exceptions that are not catched, Flink will trigger a recovery from
failure automatically[1].

Thanks for your response.
For simplicity, I want to capture exceptions in a centralized manner and
log them for further analysis, without interrupting the job's execution or
causing it to restart.

Hi Sharif,
I would like to know what do you want to do with the exception after
catching it? There are different ways for different requirements, for
example, Flink has already reported these exceptions.

Hi, community.
Can anyone please let me know?
1. What is the best practice in terms of handling exceptions in Flink jobs?

Sorry for the late reply. There should be no problems instantiating the
metric in the open() function and passing down its reference through
createSink and buildSinkFromRoute. I'd be happy to help in case you
encounter any issues.

Hi all,
I've recently been encountering some issues that I've noticed in the logs
of my Flink job that handles writing to an Elasticsearch index. I was
hoping to leverage some of the metrics that Flink exposes (or piggyback on
them) to update metric counters when I encounter specific kinds of erro
Hi!
You can open a JIRA ticket for this feature. However from my perspective
this feature should only be added to some specific connectors (mostly
message queues) and formats. You might want to attach a list of proposed
connectors and formats in that ticket.

Hi,
Thanks for the quick response.
The use case is not specific to JDBC (JDBC is just an example) but more for
custom error handling in all connectors.
How would we go about proposing such a new feature to be added to Flink?

Hi!
As far as I know JDBC does not have this error handling mechanism. Also
there are very few connectors / formats which support skipping
erroneous records (for example the csv format).
Which type of exception are you faced with? As JDBC connectors, unlike
message queue connectors, rarely (if ev
Hi,
Is there any mechanism for handling of errors produced by Flink SQL?
It can be useful for various use cases:
1. Logging exceptions and the erroneous row to a kafka topic
2. Ignoring transient exceptions instead of throwing and failing the entire
job
If there are no such mechanisms may I propo
Hi Jacob,
one of the contracts Flink has is that if a UDF throws an exception then
this means that it has failed and that it needs recovery. Hence, it is the
responsibility of the user to make sure that tolerable exceptions do not
bubble up. If you have dirty input data then it might make sense to
How do we get uncaught exceptions in operators to skip the problematic
messages, rather than crash the entire job? Is there an easier or less
mistake-prone way to do this than wrapping every operator method in
try/catch?
And what to do about Map? Since it has to return something, we're either

Hi Mich,
at the moment there is not much support handle such data driven exceptions
(badly formatted data, late data, ...).
However, there is a proposal to improve this: FLIP-13 [1]. So it is work in
progress.
It would be very helpful if you could check if the proposal would address
your use case
Hi, new to Apache Flink. Trying to find some solid input on how best to

interrupt the stream.
For example, if an error occurs during deserialization from bytes/Strings
