Hi,
I'm trying to understand how to create an aggregation query for tag distribution.
Record example:
{
@timestamp: {iso time} ,
record_type: {string},
record_data: {string},
tags: [ {key: {string}, value: {string}}, ...]
}
I want to query the data and get a distribution of tags (key, value) over a specific record type.
Example of response:
{
"record_type_1":
[
{key: "key1",
value: "value1",
count: 2
},
{key: "key2",
value: "value2",
count: 1
}
]
}
I'm not sure which aggregation pipeline should I use?
