Return the most recent record from ElasticSearch index

Question

I would like to return the most recent record (top 1) from ElasticSearch index similar to the sql query below;

SELECT         


        

Answer 1

I used @timestamp instead of _timestamp

{
    'size' : 1,
    'query': {
        'match_all' : {}
            },
    "sort" : [{"@timestamp":{"order": "desc"}}]
}
