Work Description: egalpin opened a new pull request #15381:
URL: https://github.com/apache/beam/pull/15381
Adds the ability to prevent infinite retries with non-transient
Elasticsearch write failures by providing a user-configurable setting called
(for now, I'm not certain the name is perfect) `withThrowWriteFailures`, which
is `true` by default to maintain backward compatibility.
If `withThrowWriteFailures` is set to true, the response from Elasticsearch
Bulk API will be used to capture the result of persisting a document (or
deleting it). The order of Bulk API response is guaranteed to be in the same
order as the Bulk API request[1], so we can stitch together what the write
result of a given input document was.
This PR introduces a new class `WriteSummary`. This class is used to collect
the context of a document as it passes from raw input document (i.e. the
PCollection being sent to ElasticsearchIO.Write/ElasticsearchIO.DocToBulk), the
Bulk Directive which resulted from transform settings and the input document
(ex. delete directive, upsert, scripted upsert, etc), as well as whether the
document resulted in an error from ES. By maintaining all the context/ancestry
of the document, users can get at the input document and its resulting error,
for example. Without maintaining the ancestry, we could only return the Bulk
Directive which would be less helpful in many cases.

> When streaming messages from PubsubIO , the pipeline is in Streaming mode.
> If for some reason the ElasticSearchIO.Write() has an response from the
> ElasticSearch index api, the writefn will throw a IOException. Since this
> excetpion is part of the Write transform, it becomes an unhandled error.
> This will then inheritly cause behaviour from the job pipeline to infinitely
> retry that error..
> _*snippet form beam website*_
> The Dataflow service retries failed tasks up to 4 times in batch mode, and an
> unlimited number of times in streaming mode. In batch mode, your job will
> fail; in streaming, it may stall indefinitely.
>
> This is the ElasticSearchIO.write transform .

> * input.apply(ParDo.of(new ElasticsearchIO.Write.WriteFn(this)));*
> return PDone.in(input.getPipeline());

> The pardo function (WriteFn) finishBundle step will call
