That understanding is incorrect. Solr is not a data store. Reasoning based on that false assumption leads to false statements. I’ve used Solr for about a dozen years and I’ve worked at two different non-relational database companies. Solr does not meet the minimal requirements for a reliable data store. For example, there is no transactional backup or even dump/load. If you use Solr as your primary repository, you will lose all your data at some point. On Monday, I need to delete an index with 45 million documents and recreate it from the source repository. I screwed up and made an incompatible schema change. Part of the index is written one way and the other part another way. Solr won’t even open the index now. So all that data is unrecoverable. If you need a cluster-aware data store with search features, buy it from MarkLogic. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog)
