why my query result for count is AQAABgAAAACJAgDKEAErAQE8BAIaAgP/IA== ?

my druid version is 0.8.3

this is my quey json:

“queryType”: “groupBy”,

“dataSource”: “druid_test_visitor_tag”,

“granularity”: “all”,

“dimensions”: [



“filter”: {

“type”: “javascript”,

“dimension”: “messageTime”,

“function”: “function(x) { return(x >= 1455600000000 && x <= 1456821960000) }”


“aggregations”: [


“type”: “cardinality”,

“name”: “count”,

“fieldNames”: [



“byRow”: false



“intervals”: [




and this is my result:

Are you making this query to a broker or directly to a data node (like a historical or realtime node)? The broker should finalize the aggregator if you query through the broker.

@Gian Merlino thx, i get the right result from broker.
