ES可实现按year,day,hour,...聚合。代码如下：
curl -XPOST 'http://172.16.91.34:9200/ibw_attendance_records/_search' -d '{
"size": 0,
"aggs": {
"sales": {
"date_histogram": {
"field": "start_work_time",
"interval": "hour",
"format": "yyyy-MM-dd",
"min_doc_count": 0,
"time_zone": "+08:00",
"extended_bounds": {
"min": "2018-11-10",
"max": "2018-11-20"
}
}
}
}
}'
