By way of the deprecated SolrCore.getSolrCore method, SolrCore.getSolrCore().getCoreDescriptor().getCoreContainer().getCores()
Solr starts up in an infinite recursive loop of loading cores. I understand now that the UpdateProcessorFactory is initialized as part of the core initialization, so I expect there is no way to read the index of a core if the core has not been initialized yet. I still feel a bit uneasy about initialization on the first update request, so is there some other place I can plugin initialization code that runs after the core is loaded? I suppose I'd be using SolrCore.getSearcher().get().getIndexReader() to get the IndexReader, but if that happens after a good point of plugging in this initialization, then I guess SolrCore.getIndexReaderFactory() is the way to go.

Is there any way I can get the cores and do my initialization in the @Override public void init(final NamedList args) method? I could wait for the first request, but I imagine I'd have to deal with indexing requests piling up while I iterate over every document in every index.

The request should give you access to the core - the core to the core descriptor, the descriptor to the core container, which knows about all the cores. - Mark On Feb 5, 2013, at 4:09 PM, Ryan Josal <rjo...@rim.com> wrote: > Hey guys, > > I am writing an UpdateRequestProcessorFactory plugin which needs to have > some initialization code in the init method.
