hi. i'm using ElasticSearch 6.4.1
i'm using built-in vega(3.3.1) in Kibana 6.4.1, and vega referencing designated index.
so i cant use date-based-name indices. (so i cant using Curator API.)
of course, i can re-index from 'date-based-name index' to 'designated index',
and i can set 'designated index' to vega's refering index for drawing graphs.
but this is too complex to maintain.
so i just want to delete old documents by cron or scheduler by date-type field.
i know Watcher API but i guess there isn't feature what i said.
can i do this? i want to handle this in ElasticSearch API without other script.
i searching about this feature, but most people answered 'use Curator'.
