Hi all,

So, I am trying do a simple aggregation using _plugins-filters-aggregate_. I extract data from relation database using _plugin-jdbc_ and the result is:

```
P_ID	P_DESC PROD_I	P_ID	PROD_DESC PROD_ID SPROD_DESC COUNTRY
700 ELASTIC 1 700 LOAN DESCRIPTION	1 BLOAN Mexico
700 ELASTIC 1 700 LOAN DESCRIPTION	2 CLOAN Chile
700 ELASTIC 2 700 LOAN 2 1 BLOAN Mexico
700 ELASTIC 2 700 LOAN 2 2 CLOAN Chile
|--	project --------|----------- product --------------|----sub product -------|-country -|

```

Where a **project** has **countries** and products and **products** has many **sub\_products**.

I would like this result:

```
{
	"PROD_I"	: 700,
	"PROD_DESC"	: "ELASTIC",
	"PRODUCTS"	: [
		{
			PROD_ID : 1,
			PROD_DESC : "LOAN DESCRIPTION",
			"SUB_PRODUCTS"	: [
				{
					"SPROD_DESC"	: "BLOAN"
				},
				{
					"SPROD_DESC"	: "CLOAN"
				}
			]
		},
		{
			PROD_ID :	2,
			PROD_DESC	:	"LOAN 2"
		}
	],
	"COUNTRIES"	: [
		{ "NAME" : "Chile"}, 
		{ "NAME":	"Mexico"}
	]
}

```

I have tried this:

```
filter {
  aggregate {
    task_id => "%{p_id}"
    code => "
      map['PROD_I'] = event.get('PROD_I')
      map['PROD_DESC'] = event.get('PROD_DESC')

	  map['PRODUCTS'] = []
      map['PRODUCTS'] << {
        'PROD_DESC' => event.get('PROD_DESC')
      }
      event.cancel()
    "
    push_previous_map_as_event => true
    timeout => 3
	}
}	

```

How can I improve my aggregation to be the correct project --\> products --\> sub products?

Best regards,
