Victor commented on FLINK-13025:
--------------------------------
[~yanghua] I've tested the basic ES sink in a live project I have running Flink
1.8.1 and Elasticsearch 7.3.1
I had to get flink-connector-elasticsearch-base_2.12 version 1.8.1 separately
since there isn't a 1.10.x version yet for the connector you've created.
The basic Sink does work fine without specifying the "Type" property when
creating the IndexRequest as intended:
{code:java}
// new IndexRequest(msg.esIndexName)
.create(false)
.id(msg.esId)
.source(msg.esDocumentBody, XContentType.JSON){code}
also noticed the APIbridge is correctly pining ES cluster with Default Request
Options instead of failing with a 7.3.X ES client as before, so that's good
too!! and allows flink job to start well.
[https://github.com/apache/flink/pull/9720/files#diff-f2f261e881f5618405a827796728a6a4R82]
What I'm not sure, is if it would be better to restrict or add validations to
remove the capability to add a "Type" name when creating the IndexRequest since
it's no longer supported? IDEs will display the classic "deprecated"
underlying, but for new users I think is a weird user experience to have the
connector not complained an then see this log entry when the job gets executed:
{code:java}
//
WARNING: request [POST http://localhost:9200/_bulk?timeout=1m] returned 1
warnings: [299 Elasticsearch-7.3.1-4749ba6 "[types removal] Specifying types in
bulk requests is deprecated."]{code}
If you think that's out of the scope of the connector that's fair too, but I do
think at least the example should then omit the use of the "type" property in
the builder:

]
The part that I haven't used yet and I'm not sure how to test is the
UpsertTableSink and I would like to test that out since I can see we have
"String docType," fields there and if a user provide those it might trigger an
"java.lang.IllegalArgumentException" error on ES side.

[https://github.com/apache/flink/pull/9720/files#diff-63da77546b576d0bd0b788d522fdad6fR232]
With a message like this:
{code:java}
//

But as I said, I'm not sure how to test that in a live project so If anyone can
point me to some code example or can test that too it would be awesome.
I'd figure it out, but unfortunately I can't commit a lot of time at the moment.
