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 zhangminglei / mingleizhang At 2017-08-16 20:52:34, "mingleizhang" <18717838...@163.com> wrote: 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.

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. // 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, ActivityInfo] json.put("data", element) Requests.indexRequest().index("filter-index-s").`type`("my-type").source(json) } override def process(activityInfo: ActivityInfo, runtimeContext: RuntimeContext, requestIndexer: RequestIndexer): Unit = { requestIndexer.add(createIndexRequest(activityInfo)) } })) Thanks mingleizhang 【网易自营】好吃到爆!鲜香弹滑加热即食,经典13香/麻辣小龙虾仅75元3斤>>
