Hi,
Greetings!
My requirement is as below.
I have Topic named "sample-topic". This topic contains the same keys(as
String) with multiple messages and the messages are in JSON format. I would
like to merge the JSON messages and produce a final JSON. In order to
achieve this, how to maintain the state of the previous message?
Below are the input messages in the topic.
Key : 0 Message: { "attr1" : "value1", "attr2" : "value_01",
"attr3" :"value_3" }
Key : 1 Message: { "attr1": "value_x", "attr2": "value2" ,
"attr3" : "value_y"}
Key : 2 Message: { "attr1": "value_m", "attr2": null , "attr3" :
"value_o"}
Now, I need the resultant JSON as below.
{ "attr1": "value_m", "attr2": "value2" , "attr3" : "value_o"}
Could someone help me by letting me know the solution? Thank you.
Thanks
C Suresh
