Re: Get stream of rejected data from Elasticsearch6 sink

Hi Nick,

When you get the failed data, the logic for implementing the side output is
similar to the logic for extending the
ActionRequestFailureHandler#onFailure method to output the data to other
places.

Thanks, vino.

Get stream of rejected data from Elasticsearch6 sink

[Nick Triller]

Hi all,

is it possible to further process data that could not be persisted by the 
Elasticsearch6 sink without breaking checkpointing?
As I understand, the onFailure callback can't be used to forward rejected data 
into a separate stream.

I would like to extend the sink if this use case is not covered yet.
What would be a reasonable approach that matches Flink's overall architecture?

As a new Flink user, my first intuition was to check if it is possible to 
create a side output from the Elasticsearch6 sink.
Does it make sense to support sink side outputs?

Thank you for your advice.

Regards,
Nick
