Indexing Arbitrary Key/Value Data

[Furkan KAMACI]

Hi All,

I can index such data with Druid:

{"ts":"2018-01-01T02:35:45Z","appToken":"guid", "eventName":"app-open",
"key1":"value1"}

via this configuration:

"parser" : {
        "type" : "string",
        "parseSpec" : {
          "format" : "json",
          "timestampSpec" : {
            "format" : "iso",
            "column" : "ts"
          },
          "dimensionsSpec" : {
            "dimensions": [
              "appToken",
              "eventName",
              "key1"
            ]
          }
        }
      }

However, I would also want to index such data:

{
  "ts":"2018-01-01T03:35:45Z",
  "appToken":"guid",
  "eventName":"app-open",
  "properties":[{"randomKey1":"randomValue1"},
{"randomKey2":"randomValue2"}]
}

at which properties is an array and members of that array has some
arbitrary keys and values.

How can I do that?

Kind Regards,
