Here’s a list of some sites using Solr: https://cwiki.apache.org/confluence/display/solr/PublicServers
It’s not really what you’re looking for though, it doesn’t really have the details you’d like. There are two dimensions here: 1> does Solr do what you want? You’re talking about reporting, and Solr is primarily a search engine. That said, it has tons of analytics capabilities built in. Depends on what “reporting” means in your situation. 2> how expensive is it? Here “expensive” means hardware and support. Unfortunately that’s un-answerable. This is really “the sizing question”, and there are too many variables to work with. If you want some backup for why this is an unfair question to answer in the abstract, see: https://lucidworks.com/post/sizing-hardware-in-the-abstract-why-we-dont-have-a-definitive-answer/ What I’d recommend is to ask for enough resources to create a PoC on an existing bit of hardware, your workstation/laptop would do. For a PoC, there’s no reason to even have 3 Zookeepers, I routinely run with just one (although I do use an external-to-Solr zookeeper). I’d start with two shards, leader-only, just to be sure you take into account how SolrCloud works. I wouldn’t get fancy here, just take your first guess at how it will all work and index a bunch of documents (say 10,000,000) and see if you can get Solr to create the data for your reports. At that point, you have some data to work with, i.e. how big your indexes are, whether Solr’s capabilities meet your functional requirements etc. You can infer that I consider 10,000,000 documents a small Solr installation, with the caveat that if the docs are each gigabytes in length all bets are off. I’ve worked with clients who index billions of documents/day (yes billion) admittedly they had a very large hardware budget ;). I’ve seen 300M docs (each reasonably complex and a few K each) fit comfortably on a machine with 12G allocated to Solr (64G total physical memory IIRC). So, It Depends (tm)... Good luck!
