Hello , Gordon
Thank you very much. And I do save the extra redundant the code. But I have to
write the following code as I use a spring boot tech to get the data from
elasticsearch. As refers to other codes can delete. If I do not write the
json.put("json", "JsonFormat.printToString(element)"), or I will get a map that
just belongs to a data source like "key":"value", "key":"value" which is a map
by using spring boot tech. And I can not get what I want.
json.put("json", JsonFormat.printToString(element))
So, When I add the above code, I can get the data by spring boot tech that
access Elasticsearch which returns like json -> "key":"value", "key":"value".
In this time, I can get the Protobuf object represented by a json string. Then
I can do what I want!
But the below three line of code can be removed from my project really.
json.put("activityInfo", element)
json.put("mid", element.getMid)
json.put("activity", element.getActivity)
Peace.

Hi,
I see what you were asking about now.
Yes, it doesn’t make sense to sink an object to Elasticsearch. You either need
to transform the object to a JSON using libraries like Protobuf / Jackson /
etc., or disintegrate it yourself into a Map.
One thing I noticed is:
json.put("json", JsonFormat.printToString(element))
If what you want is all fields in this object to be able to be queried in
Elasticsearch, what you could do is simply:
`Requests.indexRequest().index(...).type(…).source(<the JSON string>)`
This would work fine, and you can also save the extra redundant layer in your
sinked JSON.

Ahhh. Sorry Ted. I didnt see the code was broken. Yep, I will directly put the
text code here.
Dependency is
<dependency>
<groupId>com.googlecode.protobuf-java-format</groupId>
<artifactId>protobuf-java-format</artifactId>
<version>1.2</version>
</dependency>
And the adding code is like following. This time, although I sink an object to
Elasticsearch, I convert it to a JSON by JsonFormat.printToString(element). And
it can solve my issue as I can get my data from Elasticsearch represent as a
json string, then I can use it to show my data as a front end.
// sink the filtered data to ElasticSearch
clickStreamFiltered.addSink(new
ElasticsearchSink[ActivityInfo](configElasticSearch, transportAddress, new
ElasticsearchSinkFunction[ActivityInfo] {
def createIndexRequest(element: ActivityInfo): IndexRequest = {
val json = new java.util.HashMap[String, AnyRef]
json.put("activityInfo", element)
json.put("mid", element.getMid)
json.put("activity", element.getActivity)
json.put("json", JsonFormat.printToString(element))
Requests.indexRequest().index("filter_event_tracking").`type`("my-type-2").source(json)
}
override def process(activityInfo: ActivityInfo, runtimeContext:
RuntimeContext, requestIndexer: RequestIndexer): Unit = {
requestIndexer.add(createIndexRequest(activityInfo))
}
}))
Peace.

Did you use image for the code ?
Can you send plain code again ?

Subject: Re:Re:Re:Re:How to verify the data to Elasticsearch whether correct or
not ?
I solved the issue by adding a dependency that convert the protobuf objects
into a JSON. By adding a line of code like below: element is a PB object.
Thanks.

I looked into the sinked data which in ElasticSearch. Good news I can found it
is really right there. But but, I sinked the data is an object. But the
Elasticsearch represent it as a string. I put the related code below.
element type is an ActivityInfo. then, I wrote a java api to read the data. the
value is a string instead. I want it represented as an object of ActivityInfo.
But it didnt do like what i want.
Can anybody give me some advice for it ? Thank you very much!
Thanks

Hi, Gordon.
I am not sure about this, as far as I know. ElasticSearch often store
JSON data inside it as it is convenient to create it's index. As refers to my
code below, I stored the protobuf objects (ActivityInfo which build from
activityinfo.proto file) in ElasticSearch. And it is a binary data stored in
it. It is very strange I feel. Flink document just give an example for it's
data which type belongs to a string as JSON.

Hi,
I couldn’t spot anything off in the code snippet you provided. So you should be
ok with this :)

BTW, ActivityInfo is an PB object build from xxx.proto. And already has it's
value setted to itself.

Hi, flink experts!
I sinked my data ( PB objects ) to elasticsearch. I dont know whether the
sinked data is correct or incorrect. The codes like following, Could you help
me check it please ? Im not familar with ES. Now, I want to install a kibana to
view my data. But I dont know the below codes is correct or incorrect. I ran
the flink program. it does not give me an error. I just want to confirm.
