Deleting unwanted indexes

I've got two warm nodes that indexes get moved to beyond a set expiration date on hot nodes.

When I am ready to call a DELETE on any given index, does this need to happen on all warm nodes or can it happen on one and it will know to remove it from other warm nodes too, including any potential replicas?

I want to make sure I don't need to call this DELETE on each individual warm node for the same index.

Thanks!

Indices in a cluster are not node specific. You can invoke delete on any node and the index will be deleted from the cluster (primaries and replicas are all delete).

A delete happens on a cluster level, so it doesn't matter what node you issue it to.
