Ahhh. Sorry Ted. I didnt see the code was broken. Yep, I will directly put the 
text code here. 


Dependency is 

  com.googlecode.protobuf-java-format
  protobuf-java-format
  1.2

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.

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.

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!

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 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()`

This would work fine, and you can also save the extra redundant layer in your 
sinked JSON.
