Hello, I need your expert advice. I am thinking about running two instances of solr that share the same datadirectory. The *reason* being: indexing instance is constantly building cache after every commit (we have a big cache) and this slows it down. But indexing doesn't need much RAM, only the search does (and server has lots of CPUs)
So, it is like having two solr instances 1. solr-indexing-master 2. solr-read-only-master In the solrconfig.xml I can disable update components, It should be fine. However, I don't know how to 'trigger' index re-opening on (2) after the commit happens on (1). Ideally, the second instance could monitor the disk and re-open disk after new files appear there. Do I have to implement custom IndexReaderFactory? Or something else? Please note: I know about the replication, this usecase is IMHO slightly different - in fact, write-only-master (1) is also a replication master Googling turned out only this http://comments.gmane.org/gmane.comp.jakarta.lucene.solr.user/71912 - no pointers there. But If I am approaching the problem wrongly, please don't hesitate to 're-educate' me :) Thanks! roman
