: I was also suggesting a new feature to allow sending messages to Solr : through http interface and a mechanism to handling the message on the : Solr server; in this case, a message to trigger snapshooter script. It : seems to me, a very useful feature to help simplify operational issues.
it's been a while since i looked at the SolrEventListener stuff, but i think that would be pretty easy to develop as a plugin. The existing postCommit/postOptimizefirstSearcher/newSearcher event listener tracking are part of hte SolrCore because it needs to know about them when managing the index ... but if you just wanted a way to trigger arbitrary events by name, the utility functions used in SolrCore could be reused by a custom plugin ... then you could reuse things like the RunExecutableListener from your own RequestHandler with the same solrconfig.xml syntax. that would be a pretty cool addition to Solr ... an "EventRequestHandler" that takes in a single "event" param and triggers all of the Listeners configured for that even in the solrconfig.xml -Hoss
