basketball.json 과 basketball_mapping.json을 준비한다.

BigData/ch04/basketball_mapping.json at master · Hongmebuilding/BigData

 

아래와 같이 data를 mapping 한다.

curl -XPUT -k -u elastic:elastic -H "Content-Type: application/json" "https://localhost:9200/basketball/_mapping?pretty" -d @basketball_mapping.json

 

그리고 한번 확인한다.

curl -XGET -k -u elastic:elastic "https://localhost:9200/basketball?pretty"

 

aggs를 넣어 search 도 한번 이용해본다.

curl -XPOST -k -u elastic:elastic "https://localhost:9200/_search?pretty" \
  -H "Content-Type: application/json" \
  --data-binary @terms_aggs.json
