elasticsearch - enabling TTL on an entire index -

-

question pretty straight forward, there way enable ttl on index level. means types created under index inherit enabled ttl. on documentation said "you can provide per index/type default _ttl value follows", wasn't able request ttl on index level.

in case isn't possible, workaround can suggested ? in our environment new types created time, , data has removed after not needed anymore.

you can accomplish using default option under mapping. under index , if put configuration under_default_ applied mappings these configurations not defined under same index. 

curl -xput "http://localhost:9200/test_index" -d'{   "mappings": {     "_default_": {       "_ttl": {         "enabled": true       }     }   } }'
