Hi,
We are doing a rolling index and would like to know on the NodeClient that the new index has been added. Is it possible to listen to an event that would indicate a new index creation?
Thanks!

Yes, you can create a ClusterStateObserver
with a ChangePredicate
that encodes that the indices have changed. For the apply
override that accepts two cluster states you have to compare ClusterState#metaData#indices
and for the apply
override that accepts a ClusterChangedEvent
you can just inspect ClusterChangedEvent#indicesCreated
.
Thanks for the prompt and useful reply!
