What's the fastest manner to retrieve min timestamp from Elasticsearch indices?

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

In my opinion, there are two ways to implement it.
But I don't know which is faster, because I don't have much data to test.

Like SQL below:

SELECT min(occur_time) FROM event_*

SELECT occur_time FROM event_* order by occur_time limit 1

java elasticsearch elasticsearch-5 elasticsearch-2.0 elasticsearch-aggregation

You can run a query, with size:1, sorted by @timestamp ascending, and even include_fields:@timestamp in order to fetch back only the minimum timestamp field:

{

   "size":1,

   "sort": [{"@timestamp":"asc"}],

   "_source": {

         "includes": [ "@timestamp" ]

   }

 }
