Hello ,

I want to merge two json array based on one id matching fields and create an new array in logstash , I have two Json array data1,data2 below -

"data1 "{  
"tenant":"0",  
"city":"FLORENCE",  
"id":"AXY798",  
"state":"KY",  
},  
{  
"tenant":"1",  
"city":"FLORENCE2",  
"id":"AXX123",  
"state":"KY",  
}  
"data2 "{  
"org":"teda",  
"id":"AXY798",  
"role":"Contact"  
},  
{  
"org":"partition",  
"id":"AXX123",  
"role":"Shared"  
}

Based on matching "id" , need to create a result json array:

"result "{  
"tenant":"0",  
"city":"FLORENCE",  
"id":"AXY798",  
"state":"KY",  
"role":"Contact",  
"org":"teda",  
},  
{  
"tenant":"1",  
"city":"FLORENCE2",  
"id":"AXX123",  
"state":"KY",  
"org":"partition",  
"role":"Shared"  
}

How to achieve this in logstash ..pls suggest
