top_hits, date_histogram : allow not serializing some of the fields. #7350
Description
Hi.
I would like not to get some of the fields from the response of an API request, since it's killing my CPU time at deserialization of the JSON in the client, I commented the fields that I don't want to receive, Is it possible?
First aggregation is date_histogram, inner aggregation is top_hits, What i've tried to do is to take the last value from every 30 minutes within a date range.
{
"took" : 21,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 1715,
"max_score" : 0.0,
"hits" : [ ]
},
"aggregations" : {
"my_agg" : {
"buckets" : [ {
//"key_as_string" : "2014-08-20T12:00:00.000Z",
"key" : 1408536000000,
//"doc_count" : 64,
"found_hits" : {
"hits" : {
// "total" : 64,
// "max_score" : null,
"hits" : [ {
//"_index" : "feed_history",
// "_type" : "feed_history",
// "_id" : "de1ea495-13d1-422d-ad44-a96fb0c36af8",
// "_score" : null,
"_source":{"value":1.30655,"relatedId":2,"serverTime":"2014-08-20T12:29:59.4410307Z"},
// "sort" : [ 1408537799441 ]
} ]
}
}
}, ... ]
}
}
}
