Did you use image for the code ?Can you send plain code again ?Cheers -------- Original message --------From: mingleizhang <18717838...@163.com> Date: 8/16/17 6:16 PM (GMT-08:00) To: mingleizhang <18717838...@163.com> Cc: "Tzu-Li (Gordon) Tai" <tzuli...@apache.org>, user@flink.apache.org 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.

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!

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.

So you should be ok with this :) Cheers,Gordon On 15 August 2017 at 9:18:59 PM, mingleizhang (18717838...@163.com) wrote: BTW, ActivityInfo is an PB object build from xxx.proto.
