Erick Erickson updated SOLR-10721:
----------------------------------
Attachment: SOLR-10721.patch
Here's a first cut at a patch for feedback. At this point LOAD_COMPLETE and
INITIAL_CORE_LOAD_COMPLETE are set at the same time, I think they're somewhat
different concepts and deserve separate flags though one implies the other at
this point.
> Provide a way to know when Core Discovery is finished and when all async
> cores are done loading

> Custom transient core implementations could benefit from knowing two things:
> 1> that core discovery is over
> 2> that all cores that are going to be loaded have been loaded, i.e. all
> loadOnStartup cores are done.
> It should be trivial to add a method to CoreContainer like "isLoaded" that
> would answer the first question since you can't get past the load() method
> without all the cores being discovered. I think this is a more generally
> useful bit of information than just core discovery is done.
> As for the second, that too seems trivial, just add a method to CoreContainer
> that returns the number of entries in SolrCores.currentlyLoadingCores.
> I'll add this in a few days unless there are objections.
