How to use aggregations in elasticsearch 1.0?

hi, I have a simple SQL:

select sum(count) from mytable group by id;

if I want to implement in elasticsearch, I think I should use aggregations.
Cloud anybody give me a hint, thanks.

Assuming count is a numeric field and id is a single value:

{
  "aggs": {
    "group_by_id": {
      "terms": {
        "field": "id"
      },
      "aggs": {
        "sum_count": {
          "sum": {
            "field": "count"
          }
        }
      }
    }
  }
}

Note that Elasticsearch aggregation behaves somewhat unintuitively: to get
correct amount of sums you need to set a large enough size parameter to the
terms aggregation:

 "terms": {
        "field": "id"
        "size": 10000
      },

In Elasticsearch 1.1.0 you are able to set size to 0 to get all the results
