Andrzej Bialecki updated SOLR-10769:
-------------------------------------
Attachment: SOLR-10769.patch
This patch modifies NodeAddedTrigger / NodeLostTrigger so that they generate
single events for multiple nodeName-s that caused events within the last
{{waitFor}} interval. Consequently, the "nodeName" event property has been
renamed to "nodeNames" and its value is a List<String> of node names.
All tests are passing with these changes.
> Allow nodeAdded / nodeLost events to report multiple nodes in one event.

> I think we should consider collapsing multiple nodeAdded / nodeLost events,
> ie. generate a single event with information about multiple node names, if
> there were multiple changes to the cluster in a short time.
> Processing a single event that records N changes could help us to react
> faster to cluster changes than processing N events each with a single change,
> and with {{waitFor}} in between.
