how to delete segements?I want to remove long-ago data about localStorage

curl -X POST “http://10.209.0.140:8082/druid/v2/?pretty” -H ‘content-type: application/json’ -d @delete.json

delete.json:

{
“type” : “dropByInterval”,
“interval” : “2015-10-01T10/2015-10-19T17”
}

Hi, dropByInterval removes segments from Druid. You can take a look at these docs about data retention: http://druid.io/docs/latest/operations/rule-configuration.html and the docs for permanently deleting data.
