Hello Team,  
Need your guidance for my problem

Requirement:-  
we push the updates into our ES Index from our source, and we want to pick up those updates and further send to Kafka topic using kafka output plugin

Question: How to pick up only the updates and send, is there a way to identify the updates(new record update, update to existing record update, delete event update)

Please help guide

The Solution i am looking for is:-  
To only pick up UPDATES not the whole of index data everytime we schedule and send to kafka topic - below data sends all of data every time we send

Kafka output plugin code

input{  
elasticsearch{  
hosts =\> "xxxxxxxxxxxx01:9201"  
index =\> "testcaseindex"  
size =\> 1000  
scroll =\> "5m"  
docinfo =\> true  
}  
}

output{  
kafka{  
codec =\> json  
topic\_id =\> "POC.CASE.TOPIC"  
bootstrap\_servers =\> "[XXXXXXXX01.XX.XXXX.com:9092](http://xxxxxxxx01.xx.xxxx.com:9092/)"  
}  
}

RUN with below  
bin/logstash -f logstash-filter.conf

This is a Logstash question, so please do not open multiple threads for the same question.
