Although the idea that you will need to rebuild from scratch is unlikely, you might want to fully understand the cost of recovery if you *do* have to.
If it's incredibly expensive(time or money), you need to keep that in mind. -Todd -----Original Message----- From: Ian Connor [mailto:ian.con...@gmail.com] Sent: Wednesday, January 28, 2009 12:38 PM To: solr Subject: solr as the data store Hi All, Is anyone using Solr (and thus the lucene index) as there database store. Up to now, we have been using a database to build Solr from. However, given that lucene already keeps the stored data intact, and that rebuilding from solr to solr can be very fast, the need for the separate database does not seem so necessary. It seems totally possible to maintain just the solr shards and treat them as the database (backups, redundancy, etc are already built right in). The idea that we would need to rebuild from scratch seems unlikely and the speed boost by using solr shards for data massaging and reindexing seems very appealing. Has anyone else thought about this or done this and ran into problems that caused them to go back to a seperate database model? Is there a critical need you can think is missing? -- Regards, Ian Connor
