I have query on some of the curator actions, ex: 'Close' action. Would like to know what is the use of it . Not sure if this is the right place to ask about curator, i couldn't find any curator specific forum.
I was looking at https://www.elastic.co/guide/en/elasticsearch/client/curator/current/ex_close.html which does not have any detail on what the use of 'Close' action is. Can someone please brief me about it. On a website I found that the 'Close' action saves memory and CPU. I would like to know how does it do so.
