Hi everyone, Here [http://www.elasticsearch.org/guide/reference/api/admin-indices-update-settings.html](http://www.elasticsearch.org/guide/reference/api/admin-indices-update-settings.html) I read that "Another optimization option is to start the index without any replicas, and only later adding them". My index is relatively write-heavy, so when I reindex, I shut down the replica (it's in master=false, data=true mode) and bring it back later to receive updates in bulk. Is there any way to make replica "invisible" for the updates, but online for querying, without shutting it down? And afterwards enable it back so it will receive updates? In this period it would serve stale data, which is ok. Thanks! ---

No, there isn't an option to do so.

I see. Will it work if I just reboot the server without zen discovery or with another cluster name so it cannot join the cluster back? I will try it myself, but maybe there is something I should know beforehand. Thanks!
