*And insults are not something I'd like to see in this mailing list, at all* +1 Everyone is entitled to their opinion..
Solr can and does work extremely well as a database - it depends on your db requirements. For distributed/replicated search via REST API that is read heavy, Solr is a great choice. If you need joins or stored procedure-like functionality, don't choose any of the mentioned ones - stick with SQL. Security-wise, Solr is pretty much like all db access tools - you will need a robust front-end to keep your data secure. It's just that with an easy-to-use API like Solr, it's easier to accidentally 'let it run free'. If you're using Solr for db rather than search, you will need a secure front-end. Joy and good will to all, regardless of what tool you choose! Peter On Sat, Aug 5, 2017 at 5:08 PM, Walter Underwood <wun...@wunderwood.org> wrote: > I read the seven year old slides just now.
